[mbahr22250]

I changed the fluid and external filter on my 06 250 with 36000 on the clock. Just pulled the plug and put in about 9 qts. of Mercon SP. Now every once and awhile it slips when it shifts from 2nd to 3rd. It doesn't do it a lot. It has 40000 on it now and it's done it maybe 5 times.

Has anyone else had a problem like this?

The reason I ask is because a friend of mine just had the dealer change the fluid and filter on his 99 250 with about 100k. Now sometimes when he comes up to a light or stop sign it won't go forward. It will move in reverse. He said to get it going he put it down in first, revved it to the moon and it started creeping forward, then it took off and was fine.

My truck is stock and his has an intake and exhaust, so were not putting stupid amount of power through these trannies.
