I was just wondering if the tranny out of a 94 s10 blaver will work in a 99m they are both the 4l60e trans just wondering if there there are things that need to be swaped from one to the other or if it will just bolt right in

 

Do you have 2wd or 4wd? Same question for the '94

 

Yes they are both 4wd

 

Are they both electric shift or does the 99 have a shift cable . I just put a transmission out of a 94 olds bravada into my 94 s10 blazer and they looked the same but they where definatly different , the tail shaft on the tranny before the tranfer case was only thing different , So my transfer case is lower and I can't install my front drive shaft , until I change the tail shaft on the transmission .
