Car jumps left on shifts

[unaslim]

I have a 94 auto. On the 1-2 shift its most prevelent but will happen on 2-3 as well. The shift is a little sloppy, not firm and its shifting around 5k part throttle. On the shift the car pulls hard left about 2-3 feet.

Anyone suggest a cause for this?

tq steer?

Maybe a bad mount or bad tie rod ends...

Yeah I would have to say thats a little harsh for torque steer. Most likely what Kens1992mtxSHO suggested, suspension / steering components.

Oh cool, Im much happier replacing suspension than driveline. Thanks for the point in a direction, Ill check that out. This is my first fwd, everything else has been big hp rwd cars.

Despite my limited knowledge, I agree its too much for torque steer and frankly there's not that much torque. Besides torque steer would only occur on acceleration correct? This happens on a shift even if I lift off the gas.

Motor mount, youre referring to, correct?

Definately a broken tranny mount. Stick a jack under the drivers side of the trans and put it up about an inch, you will see it separate.

^ That makes a lot of sense

i would say check the motor mount if not then i agree with everyone else suspention

Did the motor mount test, (car in gear, foot on brake, hood open and watch the rocking on acceleration) and it looked good.

Check the trans mount and its good, no separating.

What I did find was that the driver side sub frame bolt was loose. Pass side was ok, and since its jumping left, i.e. driver's side, Im quite confident that was the problem. Unfortuneately I cant drive the car yet because Im half way through a ps pump replacement.

Well, keep us posted.

The 95 that I had for about 10 minutes did excactly what you describe and I didn't notice the tranny mount until AFTER it was totalled by the bitch in the Venture that didn't understand the difference between red and green on my way home with it.

Yeah, had I caught this thread earlier, I would've screamed subframe and been the hero, but you found it before I could, haha. I've got horrible subframe bushings, they're really chewed up for whatever reason (offroading and 100' jumps with backflips?!). I also found out that they're usually torqued well, and if you try to tighten them, it snaps a bolt, and then you have time to get angry with what you've done. So if it already seems tight, then it's tight, and you just need new bushings. Hope you get it figured out.
