My transmission likes to buck/shake/jerk (difficult to describe) in 3rd gear. It will only do this in 3rd gear, all of the other gears have no problems at all. It seems to just do it in lower rpms (between 1200-1800) and only if i am cruising at that speed and not just accelerating through that gear.

Anyone else ever had this problem??

Took it to my dealership for this exact issue. They had 4 people drive it, and said nothing is wrong. Something is def. wrong. They dont want to fix it under warrenty.

nope, RPMs stay the same the whole time. even at ~35mph in 5th if i put my foot to the floor on the gas the clutch wont slip.

Are you using the correct Dexron fluid? You know the trans fluid creates a "whipping" effect and can cause the jerk your describing. Have you taken a peep at your transmission mounts? I would try to eliminate the easy parts before digging through a transmission.

Car has 80k on her, and I will have to change fluid soon since it couldnt hurt. Transmission mounts should be fine, but when i get off work i will check them just in case. No unusual noises though.

What fluid will i need for the transmission?

Wait a second 3rd at that low of RPM's is like 18 MPH, why are you in 3rd?

Where are you even going that slow?

Haha yup, its about 20mph. But not by choice, my job and girlfriend are both in columbus so i get stuck with the traffic and low speed limits (plus ~2100 rpms in 2nd on a stock exhaust doesnt sound good cruising). I check trans mounts and they seemed solid enogh to me. Might just need a fluid change.
