95 CHEROKEE ROUTINELY DOWNSHIFTS from 4th/ovrdrv

Dear friends,

My 1995 4.0L equipped Grand Cherokee very occasionally shifts out of 4th/overdrive on the freeway - Ive noticed that when this happens - the overdrive off/on button indicator light is illuminated - do you thing this is related to the trans over heat circuit ? The engine is not overheating when this occurs ? any ideas would be appreciated.

It's entirely possible that this could be a trans overtemp problem. An overtemp condition will take the trans out of OD until it cools down. I'd suggest making sure that all radiators and coolers are free and clear... find out what could be causing your trans to run so hot.

While I don't think the trans overtemp circuit is tied into the engine temp, a higher running engine temp would contribute to higher trans temps. Consider adding an aux trans cooler?
