Question 5spd automatic "shift flare" TSB question

I have a quick question for any Saturn tech people out there, as well as anyone who had the "shift flare" TSB performed. Does the tranny have to be completely pulled to do this? I may be wrong, but I thought I read here that someone was having it done and needed a loaner because it takes a couple of days. If that is the case, I have to wonder if it is worth all that. Mine does "rev up" and hard shift occasionally between the 2-3 upshift but if it needs to be pulled and take 2 days I may not bother.

Default TSB specifics

Thank you. I just checked those 2 threads. I am specifically asking about TSB # 03-07-30-052 in the thread started by "robh456" on 10-29-03. I am trying to find out what is involved mechanically with that TSB, whether or not you have to have the entire tranny pulled.

No, it does not appear that the transmission has to be removed to replace the valve body. The control valve body cover is on the front of the transmission (as seen when looking from the front of the car), after removing the transmission cooler lines, taking the cover off, disconnecting the shift solenoid connectors and removing the fluid temperature sensor, the valve body can be unbolted and removed.

Does the shift flare only happen in 5 speed automatic Ions? I'm thinking about settling for 4, that is if my local dealer has the 4 speed Ion. I don't think I've gotten a definite answer to if the 4 speed is actually still available in 2004 models, but I think I do remember reading something about that... I can't remember. This is what happens when you post late at night.

There is no 4-speed available on the Ion. It's either the 5-speed (on the sedan), the VTi continously variable transmission (on the Quad Coupe), or the 5-speed manual.

I just remembered where I read about the 2004 4 speed Ion, and it was at my local dealers web site. I just went there, and this is the information that came up on the first 2004 Ion sedan I clicked on:

Mileage: New
Body style: 4DR SEDAN
Transmission: A4
Color: LIGHT SILVER

Could this be a typo?

Edit: They seem to have "A4" for all the automatics, but the manual I just looked at has "M5".

It is a typo - there's definitely no 4-speed auto available on the Ion. I would guess their system has no way to put a 5 in that field or something.

when they say 4 speed, maybe they mean 4 speed + overdrive.

Geezer
While the valve body CAN be replaced without removing the transaxle, there are 2 different valve body part numbers depending on the transaxle assembly part number. So if you want to have the repairs done in the most efficient manner, call ahead and see if they have both valve bodies in stock.

You might even be able to scope out the AF23 part number your self. It's on a tag on the top of your transaxle and viewable (sort of) from under the hood.The tag is just behind your bell-housing where the transaxle bolts to the rear of the engine. The number on the RH side of the tag is the transmission part number (Technically the first 5 digits combined with the 3 directly underneath- but all that really matters is the last 3 numbers):

If your number is PN#24226418 or 24226999, then you need valve body assem PN#24228787. If your transaxle is PN#24224464 then you need valve assem PN#24226260.

They will need to reprogram your Transmission Control Module as well (after the repair)

All this assumes your complaint is: "Engine appears to be over-rev briefly (aka flare) during 2-3 upshifts at light - moderate throttle openings" and they can verify the concern.
