I would test this more. Check the Fluid level and color first. make sure you do not have burnt fluid. If so Flush the system If the fuild is good. Drive 50 and not 45 or 40 and not 45 45MPH is a spot that can make 4 Speed hunt for the right gear. it is apiss poor ration... Why any tranny is still a 4 speed is beyound me. they should all be 5 6 or 7 by now... any reason why I hate car makers who are lazy...

Heck with more than 4 gears. I can hardly stand it shifting 4 times, more less 6-7 times! I think 5 gears and the alternate 2nd down shift would suit the 3.7 a little better though. IE, the 545rfe.
