I have searched and read the 80e swap for the NBS is there anything that I need to be aware about for this swap...main concern is the tuning/tcu nOt sure how to go about it on the newer trucks.

I know about the shorter drive shaft and reworked cross member. Thanks for any help need a bigger trans blew the oem at 9200mi or so...of course gm won't cover it with all the mods to the engine.

 

Guys are doing it in the TBSS trucks so I know it can be done if your current trans has a turbine speed sensor. Vince

 

there r several threads on this subject.
look up smokeshow thread
or redheartbeat on ls1truck.
just look around the complete info is around.

 

Ok thanks I did the search just found info for NBS not the nnbs thanks...don't know about the turbine speed sensor

 

Pewter.....Thanks for the heads up on the ls1truck site don't got there much
