Transmission Issues

[NastyStrontium]

I just got my first GN a week and a half ago. I was enjoying it until last night. I accelerated less than half throttle, the car jerked a little and the RPM shot up. From then on, I lost most of my power. I pulled over to check the car, didn't see anything, but then, I could barely get moving. I had to drive home in 2nd gear, because it was the only way I could move it. Even then, it took a long time to build up any speed. Now, it's sitting in my driveway and I've tried backing it up, and it barely moves. I've been told that it's something inside the transmission that's the problem and will have to take it into a shop, to probably be rebuilt, or replaced.

There was something about a temporary fix, something to do with adding washers, but they don't know how long it would last.

Basically, I'm just wondering if it's worth getting my current transmission rebuilt, or try to find one that's already done.

This was my dream car, and I'm already considering selling it now, because of this.

You may have sheared the stator support splines on the trans. It's a commom problem on a stocker. The rebuilds use a hardened stator support. The transmission is going to have to come out. It's not that big of a deal. How many miles on the car? Any mods?

It has 90000 km, and a CAI. I think it also has a different chip in it. The chip says "Eastern Perf Inc. 86-7 Dyno Chip."

There's a Pic in this Thread of a Stripped Stator Support towards the bottom of Pg.> http://www.turbobuick.com/forums/transmission-talk/336775-no-gears-i-broke-sumthing.html

If that's the problem, does it require a full rebuild?

If the trans is in good shape and it's just a stipped stator support you don't need a complete rebuild. You just have to pull the pump and replace the support. It's cheap to do if you can do it your self.

I could try doing it. I've never done anything like that before, but I could probably figure it out. I could at least check to see if it's stripped or not and if I can't do it, then take it somewhere.

Replacing the Stator is a little more involved than just pressing the old one out and the new one in. It needs to be true, perpendicular to the Pump surface, if not Pump damage can/will occur.
Very good Info here by Bruce/WE4. Towards the bottom of the page look for the paragraph titled ""*PUMP STATOR:"".>> Answer Question

I read that section, it seems way too complicated for me to do. My dad's friend is a retired mechanic and he was talking about possibly being able to temporarily fix it by moving something forward a bit with washers so that it'll grab. He also said that there's no way to know how long it'll last. If I have to pay him to fix it anyways, I'm thinking I might as well just try to find a shop to fix it properly. I'd rather not have to worry about it going again every time I drive it. Hopefully, it won't cost me too much.
