Transmission questions
I'm looking for a 2000-2003 7.3 4x4 truck, and my big fear is the transmission. I owned a 97 f350 crew 4x4 and loved it, and am ready to go back to a little newer truck.
A LOT of the trucks you see out there are lifted, and or have been used for pulling...which is natural as thats what they are made for.
I understand, and have done the things we normally would do to extend the life (add an external cooler, deeper pan, etc).
The question is: other than fluid color and smell, or lack of the items listed above, are there any tell tale signs that a unit is going to need major repair soon?
A local wrench friend of mine noticed that in some of those that needed repair asap, there is a noticible lag from the time the gear selector is placed into reverse or drive, and when the trans actually engages.
thoughts?

Also check for any shift flairs between gears. Check for what seems like late gear shifts. Feel for firm shifts (related to flairs but not as pronounced). Shift through each manual gear selection, including down shifting as you decrease speed.
Then, if it all feels good, ask for an inspection by your mechanic and have them pull the pan.

i have a 1999 f250. It shifts well, but when coasting around 38 mph, the revs drop down to idle (800rpm) and then bounce back to around 1200. If I pull the PCM keep alive memory fuse (#2 under dash), it stops doing this for 10 or 20 miles. Any idea what this could be? I recently had a problem where the TPS was reading partial throttle all of the time. Pulling #2 fuse fixed this too.
