I recently put a 4l60e back in my truck and it had been about 4 years since I have had one in it and the plugs had gotten melted by the exhaust and one had been cut by me... But the transmission I got had all the plugs with it and I spent about an hour splicing all the new plugs on and heat shrinking them on right. Now I cant get the truck to move at all in any gear. It shows the gear selector moving on the instrument cluster but the truck never moves. It has power to the O pin on the oval plug. It does throw a p0740 code though. Can anyone help me out with this? Just point me in the direction I need to go to chase down what wire I might have gotten wrong for nothing to work.

Thanks
Jon

Sounds like you might have broken the pump when you installed the trans. The electrical portion of the trans will not keep it from moving. Vince

^^^ sounds like the pump isn't working or you don't have the TQ all the way in. That happened to me once. Kicked myself to death during a four hour removal and reinstall process.

Pin O? You must mean pin E. My diagrams don't even show a pin O in the connector. Tranny power on the 4L60E is pin E. It should be a pink wire.

The P0740 code is for a continuous open, short to ground, or short to power in the TCC solenoid. I would recheck your wiring. Or, the TCC needs to be replaced.

Can I just buy another pump and put it in? I see there is a 298mm type and a 300mm type not sure witch one I need though? How can I tell?
