So this is what happens when you don't latch your bed cap down. Damn wind.

 

That sucks was it hard or soft cover?? Did it damage truck at all?

 

it was a plastic undercover bed cap and luckly no damage it was scary tho I thought someone had run in to me.

 

I like the undercover i had but noone understood why i always made sure it was locked and closed.... That is the reason!!!

 

so now I get this code any ideas?
P0741 Torque Converter Clutch Circuit Performance or Stuck Off

Does this have anything to do with the TB converter I just put in?

 

Its possible, could be a tcc solenoid too.... Need to break out the diag chart on that one....

 

which one would you pick?

1991 Chevy Truck-2500 Series (1988-2000)
Transmission



A.T., 4x2, 4L80E (opt MT1), diesel
A.T., 4x2, 4L80E (opt MT1), gasoline, 5.7L, ID BBP

A.T., 4x2, 4L80E (opt MT1), gasoline, 5.7L, ID BAP

A.T., 4x2, 4L80E (opt MT1), gasoline, 4.3L
A.T., 4x2, 4L80E (opt MT1), gasoline, 7.4L

 

A later model that will accept the nss, and has the cooler lines further apart.... I know the internals were "better" on the earlier 4l80s but for simplicity find something out of i want to say a 96 or later

 

The real early EPC solenoid in the 80E is not compatible with the newer computers. I wanna say it was 93 and back. It had a self cleaning feature or something different. Not sure if you can change out the harness and solenoid to make it work or not, I was thinking you couldn't but I forget. I would stay with a newer one 97+

 

so my son got his first vehicle today its a 81 Chevy C10 it has a 400 cid th400 and a 12 bolt rear its a long bed and he give 750.00 for it. heres a picture.
