when ur tranny went out what did u do? put another 4l60e in it or step it up to something else? o and im goin with a lq9, if its dbw can i use my throttle body from my 4.8? and my intake from my 4.8 will swap over too right? i kno that when i was lookin into the ls1 they would put ls6 intakes on, can i still do that and get better flow?

 

I swapped over everything from my 4.8 to the LQ9 with no problems. Used my cable TB instead of the LQ9's dbw.

 

how long did it take you? and who or what did u use to reflash ur pcm?

 

I actually had it done by David Heck out of Indy. The swap started at 8am and finished at around 3am. But we had some problems that were partly my fault for getting an engine with a poor pullout job. I had the PCM tuned by Wheatley. It fired up and runs great with no problems after the install.

If I had to give any advice about the swap is to bring an extra set of exhaust manifolds with screws and nuts. The stock nuts don't like to come off and you may have to grind off the screw. They are really cheap and it would have saved a lot of time if I had brought a pair.

 

My friend and me had the whole complete swap done in about 11 hours.. You can use everything off your 4.8 on the 6.0.. I bought a built tranny 4l60..

how long can i make my stock tranny last? till i have to rebuild it?

 

whats a extra set of exhaust manifolds prolly gonna run?

 

The trans will last as long as you keep your foot out of the floor board, but thats not gona happen. Best bet is before any of it you start saving for a new set of gears, good posi, a set of long tube headers, ohh ya a new trans..

When you get your 6.0 pullout just make sure it has the exhaust manifolds on it. Mine did but instead of removing the Y pipe from the exhaust manifold they just cut the pipe after the flange (becuase the nuts would not come loose).

 

o ok, o and mangled im savin up for the headers i got the gears and posi already taken care of, im hopin to have the truck with the lq9 in it by Christmas and hopefully with a good tranny, will EFILive let me reflash my pcm?
