So I notice latly that when I am in 4th gear and go into 5th it seems to stumble or vibrate whatever it is. It almost feel like I am shifting at to low RPM but this isn't the case also I notice it in 2nd to 3rd sometime it rumbles crazyly.... It feel just like it almost stalling out on me.. Anyone have ideas? They're 115k miles on the tranny

Is the vibration RPM or speed dependant, or are you able to tell?

Speed, 100% sure it isn't RPMs


Edit: I'm not reving it from N to like 2k + into 5th and having it stumble on me either

I would crawl up underneath that car and shake, rattle, pull, push, and pry, on both drive-shaft u-joints to see if there's any slop whatsoever. If not, I would STILL replace both U-Joints before I attempted to troubleshoot any further.

They're what... $8 to $16 a piece plus installation (if you don't put em in yourself).

Use precision u-joints, same thing happened to me. No more vibration over 35. Well that and a different axle.
