Help?
 

So...I think the tranny is slipping..I'll be driving down the highway..and once I get up to about 55-60, it feels like it drops out of gear and the engine shakes REAL BAD..and when I gas it, it'll slowly go up, but my RPM's will stick to like ~2k(wherever they were) and wont move until I depress the gas heavily.

To me, that doesn't sound like a slipping tranny. When I started losing third and fourth in my Trans Am, it would feel as if I was slipping a clutch. The RPMs would go up, but the car wouldn't move. My issue was my 3-4 band was toast. Like I said, it was in my TA, and I don't own a SVX, so I might be comparing apples to sardines, but I hope I helped a little bit.

Typically when the transmission is failing, cruising on the highway, under medium throttle it'll slip out of 4th/OD until the RPMs rise enough and then it will finally catch in 3rd gear. Not to be confused with normal torque converter unlock.

yea it sounds like some weird combo of the torque converter lockup and a mount that's bad or something.

Re: Help?
 

Was my first thoughts as well. rough torque converter lockup+ bad mounts will make for a lot of movement. Explains it accelerating slower and then with more gas, unlocks and downshifts.

the harness on my trans was broken at the plug, so the first time i took it out, it came unplugged, and the car shook TERRIBLY. It scared the heck out of me. I dont know if thats what your facing, but when i gave it gas, it didnt want to accelerate. threw it in nutral and still shook.

I think it's a bad torque converter.

I also think this is not the Tech Q&A forum. Just sayin.
