Hey guys,
I'm trying to chase down what the dealer and I think is in electrical issue. A new clutch (2nd time) and clutch upgrade was performed. After everything was put back together the sxs will not shift correctly and seems to go into a limp mode. Does it in manual or auto. The oil pressure light eventually comes on as well. The dealer said it was showing a code P74 and they replaced the 2 shift valves. They took it apart again and did something with the oil pump and checked for blockages and cleaned valve body. They replaced the PCM and the code remained. The clutch relearn was done but it seems like the PCM is resetting and losing the relearn state. When you try and drive it, the gear indicator acts like it just went into relearn mode and goes blank then dashes. Then gets stuck in whatever gear you where in. I cleaned the 3 ground connectors and put them back with dielectric grease. I did the same for the 2 ECU/PCM or whatever they are called connectors under the driver seat. I disconnected the 2nd battery and any ties into the main battery just incase it was something shorting out from my added accessories. Been trying to research on the forum to find other people with similar issues. I'm not sure if the oil light coming on and the shifting issues are related. The dealer mentioned when the light comes on their scanner still shows the pressures are fine. One person I saw had fixed a similar issue but cleaned out the 3 oil sensors connectors underneath the clutch assembly. I guess I need to get a service manual to find where those are. Thanks for any help.
