Gone like a freight-train, gone like yesterday
Gone like a soldier in the civil war, bang bang
Gone like a '59 Cadillac
Like all the good things that ain't never coming back
She's gone (gone) gone (gone) gone (gone) gone, she's gone

cause the wife finds out about the girlfriend

And how is that not a win?  You get rid of both of them...
cause when she devorces you she will take the truck and the house lol.

I think that moving away from the girlfriend part, I'm sure it was a joke anyway, it's probably safe to say that your transmission requires more in depth diagnosis. Besides, I'm sure your girlfriend is a very nice girl.

Lol thanks guys but she went and left me as she hated it when I brought up trucks at the dinner table. Anyways away from women I don't have the cash for a 4L80 so I'm rebuilding the TH400 in the truck already. But I found an 83 TH400 4WD that's been rebuilt. So my thought is drop my transmission and t-case, break the two apart and slap the t-case to the 83, put back in the truck and drive away. But will my 80 t-case bolt to the back of the 83 trans or would I need a new t-case? Cause those 205's are heavy lol

should of had a plan B lol. all transfer cases that come off a th400 are 32 spline. theres a long shaft and short and figure 8 pattern and round pattern. but if you have the adapter for that t case. it should be a simple swap. the 80 should have the figure 8 and the 83 should have the figure 8. you dont have to worry about the long shaft till 86 i think. so all should be good. you could even just take the trans out of the 83 and put that in your 80 with the t case from the 80

The 83 trans is the transmission itself, not the t-case too as he's keeping it. But the trans itself, that's what I want. If it will work it's going on the 80 t-case and going in the truck. If I need too I'll keep the trans and swap the guts into mine lol

They should swap with no problems. You can swap the adapters if you want or leave them. Personally I would leave them alone and just swapping the transfer cases
