Tranny rebuild kits

[sps SOHC]

Well I don't know how much life is left with my current tranny and differential (96 SC2m). I know 4th gear is getting a little tough to get into and you can hear a light whistling sound from it. I think the synchros are going.

I have a 92 MP3 tranny sitting in my kitchen, but it needs to be rebuilt. I've never opened up a tranny before but after looking through razorbak's gallery, it doesn't look too hard to rebuild. I do have an FSM to help me through it as well.

Now I was wondering if there is a kit that I can buy that has everything I need that normally needs to be replaced. Or do I have to buy individual pieces from saturn?

Also I'd like to weld the differential pin, but I have no welder. Someone told me a while back they would do it before but I can't recall who.

I expect a photographic How-To!!! That way when it's my turn I'll know how. I would think any welding shop could weld that diff pin for not a whole lot of money.

I don't have a camera anymore, so making a photographic documentary of it might not be so easy.

Check out Razorbak's gallery. He has the how-to in there pretty much, though it's not all in order.

I plan on rebuilding the mp3 from my 95 sc2 i have sitting in my garage.
I have a FSM also and would like to know if their is a "rebuild kit" available and maybe a price.

Barnowl, when I get to it, i'll make sure to do an extensive write up!!

There is a manual trans kit availible. It contains the "soft" parts. Shifter fork pads, shifter shaft bushings, seals gaskets. It has no hard parts like gears, bearings or syncros. These are order as needed items.

Wouldn't it be a good idea to replace the syncros and bearings on a high mileage transmission once you got that baby open? I'm guessing here, but you wouldn't replace the gears themselves unless they are damaged right? I wouldn't think they would tend to wear much.

i bought the rebuild kit from the dealership. it's in the $120 range and it includes all the gaskets, sealant and little plastic nubs for the shift forks if you're freshening up a tranny. if you need synchros or other gear-type parts, you would have to get them separate...

That kind of stuff is replaced on an as needed basis. During a rebuild it is suppoed to be inspected and the clearances measured. There are minumum clearances for the blocker rings (syncros) and clearances betweens gear sets. The condition of the gears and syncro assemblies is an inspection item durning a full blown rebuild. Anything found lacking should be replaced. Just replacing because you are in the trans can get very expensive.

Thanks everyone for the information. My 1st gear is whistling slightly at low (>2K) rpms. Usually only when it's cold. I guess my FSM should tell me about clearances and such to check for during the rebuild?

Just to be sure, if you hear a whistling sound for a gear (4th for me) what does that indicate? Sometimes it's hard to downshift to 4th, sometimes it's easy.
