The other day I was driving and I downshifted from 2nd to 1st then floored it and I felt and heard a noise right by my arm rest. Now when I try to floor it in any gear I get the same feeling and noise. I'm assuming it's the transmission mount, just need some reassurance.

 

possibly... crawl up under there and check everything just to be sure thats all it is...and how fast were you going when you went into 1st.??

 

is your shifter moving up and down.....probably is the trans mount...very weak and common problem...I'd bet ya your right on..bad mount..

 

20+ year old rubber mount. If it doesn't need replacement, it will.

I was going like 25 when I dropped it down to 1st. I have no problems with my shifter, it only happens when take off fast.

 

Yea, its your mount. I had that smae problem and didnt fix it. Now my tranny is screwed up and I cant drive it...

 

Damn man. I'm probably gonna fix it tomorrow.

 

how did it screw up your tranny. BTW i got an energy suspension mount and it is about a 3/4 of an inch taller, is it supposed to be that tall? Also when i put it in i had to pry the tranny back over so it was in proper alignment.

 

Just curious, but does both the T-5 and auto take the same tranny mount? I got a 88' and I was planning on either using Energy suspensions or Prothanes one thats why.

 

I have an 86' trans am with a 305 H.O. 4bbl with a 5 speed. I Think a similar thing happened to me. From a stop I burned out through 1, 2nd, and 3 Gear and I felt somthing bump the floor when I floor it. How easy is the fix? Is there a stronger replacement. Oh and a side thought I have heard that my car is rather rare. With is also being a ws6 and a borg & warrner trans and axle. Is this True???

It was the tranny mount, thanks for the quick responses.
