I've been spending the morning reading about transmission issues with the ZF 5HP24. My '05 now has a condition that is slowly getting worse. At a sustained speed, or on a hill with a gradual slope, with just a minimal amount of throttle input I can generate that "growling" sound (I don't know exactly how to describe it) from the transmission that has been discussed on here. Additionally I can feel the power surging, but the engine RPM isn't really changing. I'm pretty sure what I am feeling is slipping in the transmission. As the growling sound in the tranny gets worse, the slipping gets worse. The two are clearly interlinked. However gear shifts are still pretty smooth and with some additional throttle input to raise RPM's the sound and slipping goes away. I have noticed the occasional small jolt of what feels like the tranny catching up to the throttle input from a stop of very slow speeds. But nothing like that "slamming" into gears that others on the forum have reported.
Is impending doom in my future? Is this worth pulling the tranny and rebuilding it or am I missing something simpler? I still carry an extended warranty, so if I need a tranny swap/rebuild I'm probably going to try to get them to cover it. But I'm just curious what the opinions are here about what might be going on.
Phil! Help a brother out! If I can get my 5HP24 into my carry on luggage, can I come visit you for a week?
