Van listed above is an SE flex model. After 97K miles of flawless service, the MIL came on while pulling a hill on the freeway and downshift to 3rd resulting in "limp mode". It was over 100 degrees that day. I found that pulling to the side of the road, shutting off the engine and restarting cleared the problem and all was fine... until maybe the next hill. Problem continued to get worse but was less of problem on colder days. I dropped the pan on the transmission... first time! Filter was black and about a teaspoon of sludge on the magnet, otherwise no obvious problems... flushed fluid with 18 pints of valvoline ATF +4 and replaced filter. Problem persisted... replaced solenoid pack... problem still there... replaced valve body assembly with rebuilt unit... may be better, but is still winter.
Transmission shifts fine, though did notice some slippage on two occasions in 3rd when pulling a hill, but the whole thing is very intermittent. Now has 103K on it. I assume the transmission controller is the box on the left fender... I cleaned the contacts with nyetact electrical contact cleaner I use in delicate electronics today. Seems better. The diagnostic chart says to go for the computer next, but from what I have read on the forums... maybe time for transmission rebuild... so question is what next?
