Dizzy Swapping the VT25E for the 4T45E transmission!

2003 Saturn Vue VT25E VTI to 4T45E Transmission Swap

Here's what I have so far.

Parts Needed:
What GM Said
"They say the 2003 Saturn Vue cannot accept any other transmission, and no dealer or independent shop will put any other transmission in"
I'm sorry, but that is false information GM.

What I can Guess
4T45E Transmission
Transmission Wiring Harness
Drive Axles
Wheel Hubs
Drivetrain Control Module will need to be flashed (Cobalt)

I'm getting this together for whatever mechanic I end up taking it to as I really don't have the time (or skill level) to really do this on my own.

Any help would be great! Thanks.

2006 VUE 2.2L
Default Re: Swapping the VT25E for the 4T45E transmission!

Need to find a wrecked 2006-2007 Vue with 2.2L auto.
Pull harness for trans and all related parts. Get a wiring diagram for your vue and one for vue that you borrowed parts from. Remember GM can't program TCM without vin and don't know of any one or any way TCM can be programmed. Maybe look on some racing sites that have a computer reprogrammer that will let you set shift points your self. Why you need diagrams of both vehicles is so all signals needed from motor to trans will be there. If you get TCM with trans it should be already programmed but if something go wrong then you might need ecm as well. I do know bcm will not work.

@tiger862 - Thanks for the input, I think that is probably the best way to go about it.

Now I just need to find one!

According to GM parts book - TCM part number for 03-04 TCM is 24222126 - this would be VTI (you might confirm by looking at yours).

Parts book lists 05-07 TCM (4T45-E) with part number 24232808.

You can Google to locate possible sources.

I just did a complete swap on my 2004 vue from cvt trans to the 4t45e transmission it is possible for all of you guys out there that are wondering i did do it and it does drive.there is alot of work involved, i had to do alot of modifications cutting the cradle to fit the new trans i had to make all of my transmission mounts except for the front one which is the only one that you can buy you need a complete harness motor and inside the car from front to back because the whole wiring is completly different. the axles i ended up mking myself because i used a 2005 malibu transmission if you do do this sway get a vue trans that way the axles will work and no modifications will be needed. i didnt need to get new hubs because i used the old axles and just modified them so im not sure if you would need to buy them or not. i had to get the engine module reflashed for a 2006 because the transmission module that i got was an 06 and my ecm would cause the car to run ritch and throw engine codes. the local saturn deal can reflash its just an hour of labor the trans will work without a reflash and shift just fine the engine just wont. i can go into more depth if anyone has any questions i would gladly help you out the best i can on here but it is possible.

Good news to all those having endure the CVT/VTI transmission failures in the Saturn Vue/Ion from 2002 to 2005 and missed the GM recall. There is a valid solution to your problems, i.e., Transmission swapping from CVT/VTI to a 4 Speed Automatic or 5 speed manual, depending if you want to do the work or have someone do it for you. Most recently, I swapped by CVT out of my 2003 Saturn Vue 2.2L 4 cyl ecotec engine for a 4 speed automatic 4T45-E, which was mated also in the 2005 and up Saturn Vue. I went to Picknpull and retrieved a 2003 Alero 4 speed transmission after some research of the Ecotec engine in cars with those engines. I boought the Transmission, Wiring Harness, mounts and Transmission Control module, for I anticipated there would be some difficulty mounting the transmission. The transmission bolted to the engine, but not the engine/transmission cradle. There are 3 mounts to be concerned with. The front, back and side. After mounting the 4t45 transmission, I had tyo change the wiring harness which leads to the valve body. The harness on the CVT valve body is rectanglar, while the one on the 4t45-e is round.
The miner differences is the input speed sensor is located on the outside, verses inside the cvt or at the wheel hub. The complete wiring harness that lead to the ECU/ECM to the TCU/TCM and to the speed sensor and fuse mount must be obtained for a successful connection. The gear ratio and/or setting is already programed in the TCM from the 03 Alero. Cars that are compatible to Saturn Vue or Ion are, Chevy Malibu 04/08, Cobolt, cavalier, Saturn L200, Alero and etc. You can reflash the CVT 0 Transmission Control Unit, or obtained the TCM from the car you obtain the transmission from. Also, on the axles, you can use your own cv half joint by removing the extended axel and carrier bearing.
The ideal for swapping the tranny came from this forum.

Good! I'm about to do this swap I have a 2003 awd 2.2 Vue. Why did you go for the Alero tans. Is there any difference to other 2.2 4t45e? Is there any other advise or tip you can post to improve this project?

This swap won't work in your case. It is important to note that this swap works with FWD models, but not AWD models.

Even an AWD Saturn Vue will work with modifications, i.e., you will have to remove the drive axel for the AWD and convert it to a FWD only. I used only the 03 Alero 2.2L 4 cyl ecotec engine transmission. I had to change on the side and back mounts. The transmission bolted perfectly to the engine, but not to the cradle. I used the wiring harness for the valve body (14 color coded wires for the 4t45-e transmission vs. 20 color code wires for the CVT, Pink wire which goes to the fuses, two(2) input speed sensor and (2) output speed sensor. Any 4t45-e unbolted from the 2.2L 4 cyl ecotec engine will do, it is simply the work involved.

Thumbs Up Re: Swapping the VT25E for the 4T45E transmission!

This is an update to the VTi/CVT swap for a 4t45-e transmission in a saturn vue. After some extensive modifidications, I will provide the following.
The 4t45 will bolt up to the 2.2L ecotec. What needs to changed is the TCM control module. Rather than simply changing the TCM, you will have an option, that is, change the ECU and TCM, to a Powertrain Control module, even though some of the term ECU and powertrain (PCM) or interchangable. I will explain why. The TCM on the saturn vue (03) has a number of features that would be confusing. The Saturn TCM wire harness contains the following;

Pin/cavity wire color circuit no. function
1 - - -
2 ye 657 Trans fluid pressure sensor sig.
3-5 - -
6 pur 401 OSS low signal
7-10 - - -
11 pur/wht 5506 Ratio Contr. Motor B1 low control
12 - - -
13 D-Grn 5507 Ratio Control mtr. A2 low control
14 L-grn/wht 5505 Ratio Control mtr. A1 low contrl
15 --------
16 D-blu/wht 5502 TCC Enable Solenoid Valve low ctl
17 --------
18 blk/wht 771 Trans range switch sig A
19 -----
20 OG/blk 586 TFT senor low
21-28 ----
29 blk 452 low ref
30 PK/blk 5501 TCC Enable solenoid valve high
31 OG/blk 5504 Ratio Vontrl B2 low
32-43 ----
44 ye/blk 5500 TCC Pressure Contrl solen vav low
45 BN 418 TCC Press. Contrl Sol. vav high
46-48 --
49 wht 776 Trans. Range Swtch sign P
50 wht 5503 line press. contrl sol val low
51 d-blu 1530 line press contrl sol val high
52 gray 773 trans. range swtch sig. C

The 4t45 transmission contrains:

function pin

Shift sol. 1-2 A lt-green
Shift sol. 2-3 b yel/blk
line pressure High c red/blk
line pressure low d lt-blu/wht
+12 volt ign. e pk
Not Used f-k
TFT high l yel/blk
TFT low m blk
Trans. fluid press swt. A n pnk
Trans fluid press swt C p red
Trans. fluid press swt B R dk-blu
Input SS high S red/blk
TCC PWM t brn
TCC Release swtch, u yel
TCC Speed v dk-blu/wht
not used w

The Ratio Control Motor A and B is low circuit references. Thereofore you will have to obtined a TCM stand alone and have the module flashed and reprogramm to the 4t45 specification.

If you connect the vues tcm, it do not have the lockup mechanism to lock the Torque converter and the results would be a code in reference to Solenoid B circuit open or short. It will not allow it to shift and will be stuck in first gear. You will have to add resistors to the ratio control motor circuit which will provide the correct ratio for the gears. Initially I obtained a 2003 alero PCM and then a 2002 sunfire. These modules contains IAC coil circuits wire color blue/wht - blue/blk - grn/whit and grn/blk. however on the 2003 saturn there is not connections. Better to obtain a 2005 or above PCM. You can obtain diagram pinouts on the Ecotec forum, CobaltSS.net or scrib.com for diagrams on CVT, ecotech engines and etc. Hope this information will be helpful.

Default Re: Swapping the VT25E for the 4T45E transmission!

Hi, I'm making the swap, I did all the mechanic part, I'm about to buy the wire harness, I have some questions:
1-Should I buy the hole engine alero harness Or I will only need transmission harness?

2-Will I need the alero TCM or can I use my vue TCM and reprogram it?

3-You said you can buy the front transmission mount, where can I find it?

Thanks a lot! I will post pictures of the hole project.

Default Re: Swapping the VT25E for the 4T45E transmission!

You will have to format the TCM module on the saturn vue and place the new data for the 4t45-e transmission. That means, THE PCS function/GM function, viz:

Shift Solenoid (1-2) or A (1-2 shift solenoid valve control)
Shift Solenoid (2-3)B (2-3 shift solenoid valve control)
Line Pressure Hi (PCs solenoid valve high)
Line Pressure Low (PC solenoid valve low)
12 volt
TFT postive Trans. fluid temp
TFT neg trans. fluid temp
Trans Fluid Pressure Switch Signal A
Trans Fluid Pressure Switch sig. C
trans fluid Press. switch B
Input Speed sensor signal Hi
TCC PWM TCC PWM solenoid Valve control
TCC Release Switch TCC release switch signal
TCC Speed neg. (ground.

You have to also remember the correct gear ration
1st. 2.957
2ns 1.623
3rd 1.000
4th 0.683
Rev. 2.143

Your wire harness may need to be modified, removing the "ratio control motor (stepper motor) wiring since they will not be used." The Ratio control motor is like PWM - Pulse width Modification. If you get an Alero PCM Powertrain control module, then splicing or replace the entire wire harness, that means, that pcm will control the whole engine, including the transmission and that is a headache in itself.

You can download the 4t45 software/firmware or you can have someone at a transmission repair shop or dealership to do this. as for as the Body control module, I had no problem, providing I did not use the PCM.

"OR" you will have to find a stand alone Transmission Control Module and place it in there including the wiring harness.

PSS Picknpull or automotive wrecking yard is a good cheap source for the mount, but it will need to be modified. I drilled hole in the mount and place extension bolt with center peices to tighten it. Make sure the transmission drain pan do not hit rub against the craddle or you will have a leaking transmission to repair below. Good luck.

Post Re: Swapping the VT25E for the 4T45E transmission!

Hey Henry, Let me give you an update on your connecting the wiring harness and TCM module. First thing first/

The 4t45 wiring harness connector, see attachment. shift 1-2 and 2-3; line pressure control high/low, Initial 12V+ - TFT high/low, TFP A,C,B - PWM speed, PWM Engage, TCC Pressure control high/low and Input Speed Sensor.

Get a stand alone transmission TCM to save time office a Saturn ION 04-05
Option, if you use a malibu, alero or any other control module which combines ECM/TCM it is called a Powertrain Module, that means replacing you ECM and TCM and your saturn vue engine must be a 2.2L L6. If it is 2.2L L4 that a stand alone is sufficient. Let me reiterate that:

2.2l L6 will adopt a Powertrain Control Module i.e., Engine and Transmission control module combined.

2.2l L4 will adopt a stand alone TCM.

Additional Option, Formatting and Re-Write Transmission Control Module on Saturn Vue to reflect the 4t45 OS, which will include pinout connection.

TCC Engage is shift 1-2/2-3, but it will not shift becuase the TCM is a continuous variable, so there is not second gear. TCC Pressure Control, Line Pressure Control, Trans-fluid temp, and Stepper Motor or ratio control. Delphi and GM permitted the TCM to be rewritten.

Hoping this information is helpful in which direction you will take. It is more insight than I started with.

Sorry to bring up an old thread but looking for some assistance on this swap. Trans is in and driving. But I have some codes to iron out. Using a trans from a cobalt and a TCM and wiring from a cobalt. The cobalt parts are 2005. Need to know what wires to connect to the Ecm on the 2003 vue to the TCM from the 2005 cobalt. If anyone is still reading this it would be greatly appreciated.

Sorry for the daft first post, but I've been searching without luck so far. I have a 2004 AWD VUE 2.2 that has the dreaded cvt transmission, and am trying to determine my best course of action for a conventional transmission swap while KEEPING the AWD functionality.

If anyone here has suggestions, please send them my way. Until then, I'll keep searching.

Thanks in advance for any help.

Default Re: Swapping the VT25E for the 4T45E transmission!

I got curious on this one, even though I don't have a 4 banger engine. GM put some odd vehicles out over the years with AWD and a 4 cylinder, so something should work. I found that the Pontiac Vibe/Toyota Matrix with the 1.8 could be gotten with AWD auto trans. Don't know if it would bolt up or anything else, but from what I see, the Toyota U342 trans is AWD... A POSSIBLE answer to the AWD 4 cylinder answer???

Just a thought....

07 Vue V6 AWD LOADED!!! aka SUPER CRITTER!!! Sadly gone, and definitely missed.
08 Equinox Sport 3.6 6 spd auto, AWD, even more loaded. And the jury is still out on it.

REWARD EXCELLENCE!

That transmission won't bolt up to the Ecotec 2.2L. The Vue's ECM won't be compatible with it anyways.

It's been said multiple times. The only three viable options are the 4T45E (Hydra-Matic/GM 4-speed auto), the AF23 (Aisin 5-speed auto), or the F23 (Getrag 5-speed manual transmission). All of these tranmissions require converting to FWD because none of them have provisions for AWD.
