Thread: Tranny Question

Hello Fellow GPers

I have a 2003 GT, 3.8 no supercharge, 199k, original owner and its in decent shape other than rusted rockers.

Current issue is the trans is slipping, not all the time, but getting more frequent,

I've had it scanned and its throwing P1811 code, I know the trans will need servicing soon.

I'm deciding between having someone rebuild mine or swap it out for a GM certified rebuild trans.

Has anyone here done either of these option repairs and can you share your experience please, more info you can pass along the better.

I've been going to shops for estimates, and they are only offering rebuild or replace, nothing else.
I'm getting pretty wide quotes, anywhere from $2000 to $4000.

I'd appreciate any shop/mechanic recommendations that are experienced with GP's are honest and fair.

thanks for your time

Have you changed the filter?

Agreed with Hurtz. Like l67ss is saying, is this too far gone for a TransGo?

Might help keep it together until total rebuild. Idk, maybe you put a shift kit in already.

If there is slippage on take-offs from a stop then the shift kit won't help with that and is internal.

Yes it slips off the start, but not all the time,
I have seen a video on youtube about installing the Transgo shift kit, but I don't want to waste money on that if it will not solve the problem.

I was told from a shop that it will just continue till it stops altogether, I may wait till then.

I'm still deciding weather have mine rebuilt from a shop (yet to be chosen) or to install a factory rebuilt unit from GM,

I am not equipped or skilled to do any kind of work myself,

am looking for Calgary shops for recommendations, please

thanks all for your time
