4l80e question

[tj98gmc]

i have a friend that has a 98 k3500 6.5l diesel dually,, he is having issues with the 4l80e. took it to a transmission guy to get it looked at and its going to cost about $1500 to fix. so he has been looking for another tranny..

question is,, would a 4l80e out of a 99 k3500 454 gas truck work in his?

the guy at the junkyard says they are different from gas to diesel but cant explain why,,,

Im not 100% sure but I believe the only difference is the torque converter. I think if he uses a diesel converter he should be fine. I've read of people using a diesel Trans behind a gasser with the correct converter so I don't see why it won't work the other way.

The junkyard guy is just telling you what his computer is saying that's why he can't tell you the differences.

Swap out the converters and he should be good. Transmission themselves are the same as far as i know.....
