Installed a 2008 4L70E into my 04 and it won't shift and speedo not working
Just finished swapping a 2008 6.0 w/ 4L70E into my 04 Silverado using the Lingenfelter reluctor module plus my stock 04 computer and harness motor stayed awesome but the transmission will not shift beyond 1st gear simply neutralizes after it shifts I also noticed my speedo is not working. We already confirmed that the tranny is good by shifting it using the tech2. Already checked fuses, cleaned and confirmed all wires and connectors are good.
