I just put a 4.7 itr tranny and new clutch in my car last week. When cold or during the first 15 min of driving the tranny shifts like butter, but after a little while it gets really hard to pull out of gear and really notcchy going back into gear. Anyone have any ideas whats going on?

 

what fluid are you running?

 

if any?

 

I put 2.5 qts honda mtf when i put in the tranny, we checked and bled the clutch fluid but still after u drive around for a while everything gets really tight and hard to shift

 

Odd problem your having. I can't imagine that it would shift like butter and than do a 180 once at operating temps...I would keep this topic bumped so that someone that may have had this happen chimes in.

 

jack the car up once its warm, push the clutch, go into first and check the clutch is disengaging all the way.

 

Clutch master cylinder is taking a ****. The plundger most likely is worn and thats why when you first start driving it's fine and then slowly starts failing as you are driving it.

 

I'm having very similar problem. Was it master cylinder?

 

Ta da! Indeed it was my master cylinder.
