Put a 5.3 from a 2004 Avalanche into a 1979 C10...
Reused the original th400, so i need a manual transmission tune swapped into my pcm...i think
1979 Silverado 5.3 is the original tune

should be able to use a 5.7 t-6 tune.. then just tune ve-maf-airflow ect.. to meet your demands..Originally Posted by wzup1000

Use the stock tune and turn off all transmission related DTCs.
I have done it a few times to daily driver cars w/th350 (with weekend drag strip runs).
Not a single issue so far.
A segment swap should be better, but this way works no problem.
very good info! never thought about doing this..

the more I think about this... if the trans dtc's are dissabled and the trans does not have a vss signal.. this will keep everything in the idle area of the tune.. would make it harder to tune.. think I would stick with the manual and a vss signal..

Its not hard actually.
The VSS signal is an issue for either OS, but still is not difficult to tune it.
It is better to have a manual OS, but the auto is no problem at all.
One car I swapped and tuned is a daily driven car with TH350. The owner tells me it gives amazingly good mileage. He says no problem at all. He goes to work 5:00AM and has no cold start issues at -5 C.
He takes it to dragstrip almost every weekend and the car runs amazing. It has beaten a few stock LS1 camaros.
He shifts at 6500 RPM, and so far not a single problem.
This is the car

New one, 2005 5.3L stock:
Consider the combination. Stock or mild cammed setups may not mind having the VSS skipped and running on idle timing, but once that cam size goes up (or converter gets looser; etc), things change and you will want the VSS. M6 calibrations work well because you can force the clutch input to see clutch-out and the throttle cracker will work during decel. With no VSS, I don't let IT's learn at all since they will learn at cruise and then be wrong at idle. Just make several passes over idle airflow and set STITs limit to like 0.3 in all warm (operating) areas to minimize.
