Manual to auto swap can it be done

[Fatnasty91]

Truck is a 99 he said 5.3 but I think 4.8 but it has a manual that's messed up and I want a auto can it be done

[kewljay223]

of course. why not??? they came in automatic too... just get all the mechanical parts needed, harness for the trans and a retune. i assume you will need to swap steering columns or somehow mount a floor shifter. if u just get all OE stuff, should all bolt right in.

So u do have to buy a transmission harness and different fly wheel I assume but I was told that when a ls engine came with a standard that the crank in the engine would only allow for a standard trans fly wheel is that true?

some of that is true. Early 48s had a different crank that were matted with the manual trans. Later yr motors no issues

thinking only the 99 4.8 had this issue
