i bought a truck last night for dirt cheap its an ext cab short bed 4x4(floor shift) silverado NBS. i got it for so cheap because the trans was blown. i have a good trans out of a 99 blazer 4x4 (push button 4x4) sitting here im wondering if it will swap right in if i use my t/case? i dont know if the bell housing is the same for the lsx as the blazer was a 4.3 (i know the bellhousings unbolt). so can i swap this trans in with no problems? im sure id have to use the lsx flexplate and converter right?

plans later on for the truck are to swap a 6.0 in and a 80e but that wont be for a few months and i need to get this truck on the road for now. so are they compatable? thanks in advance

 

I would say if the truck you bought has a 5.7 then yes it will work. 99 trucks in some cases did not have ls1 engines so it might work depending on what you have. HTH Vince

 

its a nbs 4.8

 

Sorry but the bell bolt pattern, input shaft, stator and converter are different between the two transmissions.
