Is the tranny electronical or manual operatad.
Is there a Data link conector on my truck which i can read, if yes where is

Answer: You should simply pay to have a scan and diagnosis. Time is flying by while you ask a bunch of non professionals your problem. It is good to have the codes pulled, but this is not a very sophisticated system, so don’t expect much information.

You have more serious issues going on here. When you have a combination of no reverse and a bad 3rd gear slippage, it narrows the problem to the direct/3rd clutch pack. This is either a burned up/damaged or worn out clutch pack or drum, or, the apply piston is cracked in the 3rd clutch drum.

The cure is as such: If you have a 1991 transmission, you have a very early model, which would not have any updates unless it was rebuilt properly. Properly is the operative word. Properly means using the updated piston assembly, not a good used original equipment or stock new one. Get it?

The other issue concerns using the correct and effective updates available now to correct why the piston cracks in the first place. Without actually examining the vehicle, there is no way anyone, even me can diagnose your problem. If you get it diagagnosed and you need a replacement transmission, make sure you replace it with the best transmission available.
