Hey everyone.....i have a question about my tranny..... well first off today was way hot in NYC with that said i have 31,502 miles on my 3.9 LT3 and this only started today in this heat..... when i was in drive and about to park the car i shifted to reverse and to my shock i got a hard bang and movement like the whole car Jolted. i put it back in drive and not so hard bang like almost normal shift then tryed it again a few times with the same result.....what can this be it it serious???? i thank you for your help! ooooooo and also when driving it shifts perfectly fine no problems at all!

 

Comeon Please anybody????????

 

Did you park it at an incline? That tends to happen when the e-brake isn't set and parked at an incline.

 

nope no incline or hill Just regular streets i have bad motor mount or mounts maybe it could be the engine moving violently??? Idk i need answer guys!!!!!! oooo and thanks for responding!

 

honestly, I wish I had an answer, I have the same car and I hate to hear stuff like this, my car has 56000 on it with really no major problems, but I am the second owner.

this is probably not the answer but there is a power steering recall on these, did you get a recall letter yet?

 

Thanks for responding I didnt get a letter and had no idea! wow im surprised! Can that have any effect on the tranny does it sound like the tranny is going bad??

 

and im the second owner as well with 31,000 miles on it the motor mounts are bad and i need 2 new tires in front cause of bad wear looks like the guy before me abused it badly

 

maybe the bad mounts could be your answer? I wish I knew more, there are a few members here with the 06 3.9 and a few others with the 3.5, hopefully someone can help you. there is a recall though on the power steering cooling lines. here is a link to another member who had a power steering issue. I hope it helps and please keep the forum updated on what you find out, thanks

Since you already know you have bad motor mounts, that COULD be your problem. You could possibly have a bad tranny mount??? Also, are you waiting a second for it to fully engage in reverse or drive before you hit the gas? Sometimes if you throw it in D or R and hit the gas, it will clunk into gear, you need to give it a second to engage. Once you feel that slight bump (not a jolt, just the feel of the tranny engaging), then its in gear, and you should be fine.

If replacing your motor mounts (or tranny mount) does not fix it, and you are giving it a second to engage, then the next thing I would try is dropping the pan, changing the ATF and Filter (be sure to use Dexron VI). At 31K, its about time for a tranny fluid change anyway.

 

i agre with mamonte on replacing the trans mount as well also droping the pan ans changing the fluid. it will cure it imo but baby it till you have the chance to do every thing.
