98 tj 3 speed

I have a 98 tj with a 3 speed auto tranny. Whenever I first start it I think the clutches are slipping then is doesn't happen again unless I leave it alone for a good amount of time? Help?

That just sounds like a leaky check valve located on the transmission cooler hard line is leaking. When it leaks, the ATF can drain out of the torque converter which slips until the pump has had enough time to refill the torque converter. Before starting out in the morning, first shift into Neutral for 10-15 seconds or so so the pump will run (it doesn't pump in Park) and have extra time to get the torque converter refilled with ATF.

this is exactly what my 2001 tj 4.0 auto is doing..
glad I found this thread..
I hope this is my problem also.i was told by a friend that mt pump is going bad that means a tranny rebuild however I was told my the previous owns that the tranny was rebuilt 3 years ago but got no proof of this.

What is the recommended repair for this..
