hey guys! hope someone on here can help as many of you have had issues with your tranny. i have a 2006 monte carlo ss with 54000 miles and this past weekend while driving i felt a jerk. i only feel the jerking at takeoff from a complete stop at light throttle. the car seems to be fine if i use full throttle. it doesnt do this all the time just 2-3 times the whole time while im driving. i have checked the dipstick and fluid is still red and full but it does have a burnt smell. one other thing to mention, i did you drain and filter on the tranny around march/april. i used mobile 1 synthetic tranny fluid. well i figured out that it wasnt dexron 6 after i finished the whole process. my friend, which is a chevy mechanic that helped me, and i asked a few of his co workers if they was ok. They all said that it should be fine. is the mobile 1 messing up my tranny? should i drop the pan again or flush it this time? please help!!!!!

 

From what i was told, flushing your tranny will more than likely kill the transmission in these cars. Why? I have no idea. My tranny just gave out on sunday and its out of warranty but im trying to see if i can catch a break through GM and get it fixed. Like the guys told me, get a transmission cooler and a shift kit

 

yeah they qouted me at 3000 for a new tranny and labor. that sucks. i guess i will just drop the pan and check for shavings or anything foreign. hopefully i still have some time on this tranny. i do plan on getting a cooler but where should i get the shift kit?

 

its a site called 3800 performance or something like that. it was a guy selling his for 100 but by the time i checked, it was gone lol. yeah these cars suck when it comes to transmission

 

It is real important to only use GM Dextron VI fluid in our transaxles. Do not flush our tannies with a machine. Just drop the pan and change the filter. While doing that, I recommend trowing a shift kit in there. It is pretty easy.

If that doesn't fix anything, then I guess it only cost you $120 and some time but I highly recommend the shift kit and cooler regardless of the solution to your issue.

 

I got mine from Dave at triple edge performance.

 

Never EVER use synthetic fluid in a 4T65 tranny. All it does is **** them up. As said above, gotta use Dexron 6 exclusively.

Now, that said, I don't think the fluid is causing your clunk problem. It's quite possible that the torque converter clutch is going south (VERY common) and the material from it circulating through the trans.

A built trans from Triple Edge is about $1650 + shipping and core. A good shop will probably charge around $500 or so to R&R. So, for around $2000-$2200, you can have a trans with all of the goodies, and you won't need to worry about it again.

so i have a feeling my trans is having suicidal thoughts now. shifting late when in automatic mode. hard to put in gear. so is it cheaper just to buy a performance trans. i think its call tep? or something?? i know NOTHING about transmissions. but i would like to get a better performance one especially if its cheaper. i just dont know what exactly to get

 

Dextron 6 is synthetic. 99% sure

 

100% sure...
