Keep burning TCMs..

[turquise1]

Internal harness inside the valve body is new. I replaced it after I rebuilt the valve body. No, I worked on the valve body to solve the transmission delay issues. I did not have the 'no gear display, no crank, no start' issue then. It happened after I replaced the filter one more time. Everything was actually working after that as well. I moved the oil level sensor cable back to it's place and I think I fried the TCM then. I turned the car off, lowered the lift and that is when the 'no gear display, no crank, no start' issue started. The neutral safety switch cables were old and messy so I blamed that and replaced it which did not solve the issue. It was solved after I replaced the TCM then. I checked all the connections inside the DME / TCM box and they looked ok. I also sprayed them with some electronic claner.


Thanks for all your help and ideas once again..

check all the connectors and clean them. Did you replace the cable that goes from the TCM to the transmission and where does the cable for the selector switch go?

Symptoms say cable problem but that can also mean solder joints inside TCM you can open that up, I think on TCM need to drill out a could rivets. I opened up mine when I thought TCM was the problem before I figured out it was the connector.

Maybe your connector is not seating completely etc you need to determine if the connection is the problem

Fixed.. The neutral safety switch cable connection was loose. There is a part of the socket that you need to rotate to lock the connection and apparently it is not functioning well because it is partially broken. I need to either fix that or use zip tie keep things together..
