Hey guys
I have yet another question about overdrive problems, some days ago my transmission got stuck (96 XLT, 4R55 I believe) It wouldn't move at all, with the engine started if I switched to R or D the engine just suddenly died like the tranny was stuck or something. After a few attempts it start moving and I could get the truck back home but it couldn't barely move. After that I've had some problems like delay shifting and not engaging properly. The overdrive works sometimes only, sometimes it just won't go into overdrive, the O/D Off button does nothing when you press it, no light no downshifting. After more than a week of reading several posts of similar problems I decided to do some work myself and go ahead and replace the EPC solenoid, went to the dealer and bought one, remove the pan and notice the parts were not the same!!! Well' I ended up just changing the ATF and filter since they recognized they sold me the wrong part and they don't have the right part in stock, it will take a week and it's $250 CDN.
After th ATF change the truck shifts just fine, right in time and the tranny seems pretty smooth. The O/D fuse in the driver's panel was blown, I replace it but I still have the same problem with the O/D Off, not working, no O/D Off light and not going into 4th gear. Could this be be something electrical or there's a problem inside the tranny? I notice that the O/D light starts to blink 5min aprox after I press the O/D Off button while driving. If I don't press the button the light stays off all the time and doesn't blink.
Any ideas where to check?
regards
