ok, i just got the car a few weeks ago its an 86 firebird 305 5spd, when i accerlate in first or second gear the shifter lifts up about an inch or more, anyone know what i have going on here?

 

I'd guess your tranny mount is shot. 30 minute repair if the bolts come off willingly... the mount probably $25-$50 depending on which you choose.

 

which i choose? i could just take one off another car right? install it myself for free?

 

A rubber stock replacement one is at the lower end of the price scale. It will tear eventually, just like the original one did. A urethane one will cost more, but last forever.

 

My '97's shifter moved a lot when I bought it, so I got a Polyurethane tranny mount from Energy Suspension, I think it was $45 from Summit. The polyurethane ones don't have a lot of freeplay so you get more power down to the ground. The only real disadvantage is that there will be a little more road noise transferred to the chassis and the first 500 miles or so while it breaks in you will feel the engine vibrations a lot more. Overall a great mod in my eyes.

All you really have to do to swap them is support the tranny with a jack, losen the crossmember bolts, remove the old mount, bolt in new mount and tighten up all the bolts.

 

thanks for the advice guys, ill go with the poly urathane

 

I installed a new transmission mount, that was the problem, it was very easy to change, i just bought a replacement it was $6, took 30 min to fix

 

Yup....I had the same issue 3xs with the OEM rubber one on my '86 T/A. The 305/700R4 was brutal on it. I broke down and got a Energy Poly mount and it has lasted through 3 trannys, a 355 swap and 9 years of use. Best $25 ever spent.
