Default My Tranny got spooked, screen shot inside

This all happened last night. Dont know what happend. Numerous times i lost 1st-4th gear. Then whille taking off from a stop the truck was in 3 rd gear, then some times in second. I have heard of 2nd gear take offs but 3rd gear take offs is unheard of. Tranny was also shifting abnormaly HARD during it's fit. WTF??

Then stopped for gas, filled the tank and the truck ran perfect. like nothing was wrong just the SES light on.

All of the electrical codes sound like the trans is losing power to the solenoids which would explain the no shift. I have had several trucks in the shop with similar problems and the white wire of the ignition switch either goes dead or has a low pwer condition. If you drop the panel under the column and then look at the 5 wire harness that plugs into the drivers side fuse fuse box. There will be a pink orange yellow brown and white wire in a black plug. Changing the ignition switch will fix the problem. Or you can splice the white wire into the pink wire which will also fix the problem with no adverse affects other than being cheap and easy. At the shop I just change the switch to CMA.
