Error code P0743
Hi guys! I'm still having issues with my 99 Suburban. on the 4th of Jan, the tranny emptied itself on a freeway in the middle on the night on a freeway. since then I have replaced the tranny and the torque converter with a rebuilt one. My original trans was showing a code, P1870, trans component slipping but the new one came up with a P0743 Torque Converter Clutch Solenoid. I drove the truck 131 kms before it too cooked itself and spat fluid out on a hill.
The shop I bought the TC and the Tranny from says that it must have been my fault during the installation, but I really can't see it. The shop and I had words, VERY strong words, because he didn't send the tranny when he said he would, and now he is getting smart assed about the whole thing.
I really want to know what would cause this error code and is it something that I could have done? The trans is now at his shop, but he said he will look at it in his own time.
