Here is the TSB:

02-8-2 APR 02 A/T - Slipping/Delayed Engagement/DTC P1762 Set


Can anyone tell me anything more about this? I have a 99 explorer, 4 door, and I have a little automatic transmission slipping now and then. It is only when the car is warm and happens one time. When I am driving away at a slow speed it seems to pop in neutral and then "catch" into gear. It drives just fine afterwards. My factory warranty expires next week so I would like to see if I could get something done this week yet.

 

Depending on who your warranty company is and whether or not your policy has an exclusion for "items that the manufacturer has issued a TSB on" like Warranty Gold has, you probably won't want to mention to your warranty company that there is a TSB on the transmission nor do you want your dealer to. Warranty Gold screwed me out of a bunch of repairs on my Explorer because of that exclusion in my policy. I got the best coverage that they offered (Diamond Plan) which according to their literature covers everything on your vehicle except for the few items listed.

Anyway, here is the beginning text from the TSB:
