Hey guys, its been a while.

I'm in the process of finally selling my car, (tear drop), but before i do there's a couple of things I need to know.

So recently my car starts to feel funny when I push the gas, at around 20 to 30 mph I feel this struggling viberation. After passing 35 mph and above the car flies with ease. It could be the transmission but I'm not entirely sure. Of course it could be anything but since this car has had viberations for a few years now when i leave it on drive I've gotten use to it. (trust me, I've been on this forum of many years and nobody has never given me i solution to this problem, I've taken it to mechanics and they have no idea why it viberates on drive.) Age could be a factor as it is a 94 auto with 166XXX miles to boot...idk.

Once or if this gets resolve I have a question? How much can I sell this car for?

 

Manually shift it and see if the vibe is still in place.
Cold be the trans/car is shifting into OD and t/conv lock-up with a light throttle.

If vibe is still in place, check U-joints for their mechanical condition.
Should be no movement in any direction.

 

Check to see that your transmission mount has not split or separated, it's an easy swap if so.

I would also recommend having your car inspected at a dedicated driveline shop, similar to this:

it may be the driveline is just not lined up right. there is a fairly small pinion angle range that it will not vibrate on. do you have a stock transmission mount. poly mount will transfer vibrations much better.
