another e40d question
I recently purchased my dads truck. Im having a wierd shift around 40 mph after truck and tranny is warm. it will up shift then seem like it down shifts or gradually slides into gear. shifts fine cold. its a 96 psd
. My dad had the tranny rebuilt about 10k miles ago. He doesnt pull anything with this truck anymore.
I also notice that the speedo bounces 2 to 4 mph around 35 to 55mph. I read the vss
also causes shifting issues so could this be a possibilty?
I hooked up auto enginuity and have no codes. solenoid 1 and 2 seem to shift correctly. not sure if there is a solenoid 3 because values didnt change.
I did notice however the tranny fluid is really high. It is over the hot mark when the tranny is cold.
Could the possible air agitation or overfilling cause that wierd shift?
Also the auto enginuity program monitered tranny temp sensor in volts. Does this tranny even have a factory temp sensor?
