    I can't find any prices on what this stuff goes for. I don't think I'm gonna use any of it, I can't find a TBI 454/4l80 ECM and harness, and don't want to go manual v/b, or spend $700 on a standalone computer. The motor/trans is out of a 96 3/4 ton 2wd, motor is a GM crate with 30k-ish miles, and I think the trans was rebuilt when the motor was installed. Motor/trans is complete, ECM and harness would be included.

    Since it's complete, should be the same as if you were swapping it into an older truck....

    It will bolt up no problems, and since the 700 isn't computer controlled, the trans will work. I think the only thing that you would have to do is for the VSS, I think the engine computer would need a signal to work properly?? It could be for the speedo.....

    Good rebuilt trans, 30k Vortec engine. I'd say a little over $1000. Say $1500 I guess. A decent core 4l80E seems to go for around $500. Decent low mileage complete Vortec with computer and all would go for a little over $500. Figure on the rebuilt trans, and everything all there, $1500 sounds right to me. But thats just my thought process.

    What would be the purpose? Trying to use the harness and trans with your 454?

    I think Im still getting Eastcoast4wd's 92 Blazer, he swapped in a Vortec 350 with the 4l80. The 454 in my 89 runs perfect, and want to put it in the 92. But being a Vortec and non Vortec, of course they won't work. So if I can sell the motor, trans, harness and ECM, it will recover some of the cost of buying the truck. I wanted to keep the 4l80, but since this isn't gonna be a d/d my TH400 will be fine. So $1500 is a fair price????
