Thread: 01 GP GTP will not move in D or 3

Moms car
138k
will not move in D or 3, you can start it out in second but once you're moving you can shift to third gain speed and shift in to drive like normal
Checked fluid it was low, I added a quart issue was still there.
Its getting scanned by a trans shop Wednesday but I just wanted to brainstorm here.
I was thinking shift solenoid or forward bands

this could be the 3 rd forward band break in as many days.

morning bump

Well I drove it tonight..
Started out in 1st and it feels like it is slipping the entire time, once above 25-30 you can shift it to D and it will shift to the gear but will slip and bang out of gear and back in. Once you stop you have to start in second or first again. Also note: you have to let off the gas and then shift if it bangs horribly. At this point I think it might need a rebuild. Another 4T65E HD down

It is the forward band. Almost positively.

Yep

I ordered that and a master overhaul kit from TEP for both her car... and mine..

Might want to get a new 2-1 manual while you are at it if you used the car that way for a while.

So I took the trans apart replaced all the clutches and the 3-4 band




I needed one little seal from the dealer and on the way to the dealership THIS happened to my car Cylinder 4. the car saw 13* of knock -_- I guess I am doing a compression and leak down test when the motor comes out of the end of the month.

That's the exact piece that broke off my band haha it fell out when I dropped the pan.

Chipped piston?

Dont think so It runs smooth and still pulls fine, but I wont know till the head is pulled or I do a compression test. It was caused by a SH! TT Y Caspers electronics injector wire, damn thing popped off..............

It was real easy for me, I had a 35 year GM Mechanic vet guiding me step by step. This was my moms car I get to do the same thing to mine in two weeks

that would be the only way id open one up., good guidance is a must. side by side, even better.

It's not that bad Scott. If you have the right tools and take your time as well as take a lot of pictures of your progress, it is a walk in the park.

It's really not too bad. Grab a blown one somewhere and open it up. I learned a great deal tearing mine down.
