transmission

Hey all. Im having some issues with my transmission, specifically the 4T65E-HD in the gtp. I can put it into gear, drive, reverse and all of those and it will move for a few seconds, but then acts like it's in neutral in any gear. Only way to fix it is I can turn the car off for a few minutes...

When I bought the car around 6 months ago (204k miles) it had an occasional hard/delayed shift into first gear when I’d take off at traffic lights from a complete stop and then it started slipping a few weeks ago and as of last night it’s pretty much stuck in neutral. There has been no...

I replaced my starter and neutral safety switch in my 1984 Pontiac Fiero that I just bought. It’s an automatic and I can’t seem to figure out what the problem is. I’m assuming I unknowing bumped something the wrong way. Does anyone have any ideas or suggestions? Will I have to drop my...

Hello everyone I am very new to working on old Pontiac’s and I am looking for the easiest way to swap my turbo 350 automatic trans with a Muncie m20. From the little research I did it seems fairly simple considering the drive shaft is the same for both transmissions. Will I run into any problems...

On my 73 Ventura with 350/M-38 (TH350 I guess?) I was ready to change the fluid and filter but to get to the 2 rear pan bolts the transmission mount is in the way. Am I correct in assuming the transmission has to be supported and the rear mount removed to access the 2 rear bolts? I'm thinking I...

Does anyone have any experience changing the Transmission Cooler Lines on a 1999 3.4l Pontiac Grand Am. Looks kind of straight forward but never a bad idea to ask those who have already done it and may have some tips for access to the lines.

2008 Grand Prix Neutralling out between 1st & 2nd 2008 Pontiac Grad Prix. no check engine lights on at all, 3800 series III engine shifts strong through all gears drives smooth no real issues with the exception of occasionally it neutrals out in first gear or when shifting between first and...

So, I drive to a gas station, pick up a couple of things. Come back to my car and find that it has rolled back out of the space while in Park. I am able to start the car but the shifter will not engage any gear forward or reverse. I had no prior warning of transmission slippage or any other...

Ok boys. Mother of all troubles is here again. Drove out in the morning. Something snapped under the hood, car started to shake like crazy. Flood of ATF on the road and some metal pieces under the car. Satellite Differential cover torn apart form tranny Tranny was "rebuilt" in Nov 2014...

Hi everyone so basically i have an issue i believe with my clutch. I drive a 1998 pontiac sunfire GT model with a 5 speed manual transmission. I am just going too type the symptoms of whats going on with my car thats the only way i can explain. So before i start this only happens in winter, or...

I have searched and asked around everywhere but a online forum and I really hope someone can offer assistance. I have a 68 Firebird with a unconfirmed T-400 tranny. The engine that came with the car turned out to be a 1970 350 engine. I have completely rebuilt the engine and everything added...

I went today to pick up my GTP 3.4 valve after having a new transmission put it, before any work was done, Edwards Transmission did a computer scan, the only issue was the transmission. I went today to pick up the car and I had them run a scan on it and now it is showing a misfire on cylinder 6...

I have a feeling its either the slave or clutch disc. there is no visable leaks, the fluid is full, does have full pedal(its not on the floor), it slowly went from smooth shifting to hard shifting to no shifting(cant put into any gear, grinds when forced). what you think?

I've got a 2005 Pontia Montana. Not the SV6 model. On the websights it says that they are suppose to get 8L/100km highway driving and 12L/100km city driving. I get about 12L/100KM highway driving and I think about 15+L/100km city driving. Mine has 92,000 KM so it's still fairly knew. I...

2002 Grand Prix: After stopping at a light, I had no acceleration. I had to stomp on the accelerator to go 5 mph. What should I look at first? Fuel filter? Tranny?
