My transmission shifts hard, I ran some sea foam trans tune through it and changed the fluid and filter. It still shifts hard, it also sat for over a year with only being started occasionaly. Is a flush that much different then running some cleaner through and changing the fluid?

You checked all of your mounts yet?

Sorry to go off on a tangent, but how does one go about doing that, exactly?

Changing your fluid and filter will only get 1/3 of the fluid. A flush will replace all of it.


I agree. Check your trans mounts. Get the car up on ramps, and get a 2x4. Try to move the trans/engine around while watching the mounts. Look for damaged bushings.

also you can feel the jerk if you have the car in parl, change the gear to reverse. If you do feel the jerk, possible motor/trans mounts are needed.

I'll give that a try this weekend, I have a feeling that might be the culprit, thatnks for the help!

i am pretty sure that sounds like a trans mount
