I my 928's transmission is in need of a transmission rebuild. I've rebuilt several engines and smaller gear boxes in the past. I've decided to dive in and tear it down personally. I've got access to a lift and tools to get the Trans out and the room to rebuild it. Best of all my wife is the one that is encouraging me to try! What the heck. If I can't figure it out I've got resources to have it rebuilt by a pro. Besides I want to know why it died! Am I nuts? Ok let me have it! My deadline for this is sharkfest! In October!

Not to say you can't do it, but it is so much easier to crate it up and send it to Greg Brown.

At least you will know it is done right and at a fair price. Most of all, you won't have to worry about your transmission for many years.

I have a German rebuilder locally that is able to do the work if I want. I guess I am looking at it as a challenge . Five years ago I rebuilt my 944's engine myself. I've rebuilt most everything in that car too. I'm kinda excited.

And so it begins!



LOOK MA NO WHEELS!




Found a video on youtube on how to remove the whole rear suspension in one shot! Super easy!!

Today I pulled the transmission out of the car. The final removal was very simple with the help of a tall transmission jack. I've loaded it into a truck to take it to my place to tear it down. The body seems kind of empty without the transmission, suspension or exhaust in there. But one step at a time!

The Forgotten On

It's looking great so far. I hope the internals are still mostly together in your trans.

Also, have the torque tube rebuilt while you are in there. It will be much easier now then later when you have everything back in the car.

You could also do the rear main seal, etc as those parts are much easier to get at with the transmission removed.

Great going, I like people who go for it.

How many miles on your 928 and why were you sure it needed a rebuild?

I ask because i've had automatic trans vehicles seem to need a rebuild
when a change of fluid was all that was needed to restore proper operation.

Dirty old fluid (gets thick) and doesn't pump well.

sstrickstein

I had a Trans cooler fail about a month ago. It shot coolant all through the unit. Even though I changed the fluid three times the operation was never the same. I even rebuilt the valve body first. When I pulled the Trans pan the last time it was full of clutch dirt and my filter had completely fallen apart. My Trans would not shift out of second . And finally I lost all drive. Car has 130000 on it and I just decided to go for it. I'll have to make a jig to hold the unit upside down in my tool cart and come up with a way to tear apart the clutch packs. I'm excited to see what's under the skin.

Ask your local guy you mentioned in Post #1 if you can borrow his clutch pack tools. Alternatively, see how much he would charge to refresh the clutch packs for you. IIRC there is a seal inside the clutch pack housing the requires drilling out retaining plate rivets and using small countersunk screws to re-assemble. There was a post here that had pics of the process. Can't seem to find it just now (especially with the "help" of the RL search function.)

I have read several manuals on the tear down. No drill out was needed. I'm going to fabricate the tool I need to press the clutch out of PVC. And use my hydraulic press at work. Today I'm going to make a jig to hold the Trans while I tear it down
