Please help me understand this. Five or seven years ago I I bought a high mileage Wrangler with a standard 3-speed automatic transmission. After two changes of filter and transmission fluid and minor tigntening of the front band over these past years I assert that all is now well in the forward direction.
Reverse, however, remains a problem...but only when cold. No problem at all after a five minute drive. On a cold start I might be able to gun the engine and have it lurch into reverse. Also, if I let it idle in Neutral for a few minutes it might then be able to hard-shift into reverse with a mild clunk. Seemingly this warm-up behavior only occurs from Neutral, not from Park, but that's just a hunch.
I can live with this reverse situation, but I'm just curious about what the actual failure mode might be. Does anyone have any ideas? Any pointers to online "how it works" documentation?
