Tranny swap
 

So the tranny in my k5 now is a th350 with some sort of adaptor to bolt it up to np208, the blazer originally had 700r. The tranny is ready to die and I dont know what will bolt in easiest now. I was told a 700 would just bolt in no big deal and I was also told a th350 wont work easily because the adaptor is attatched to this tranny? I want to have the tranny built while still driving this one around. Can anyone tell me what kind of adaptor this is? I hope that makes sense :crazy:

What do you use the truck for?
How often do you tow with it?
How much money do you have to fix this with?


Theanswers to those 3 questions should answer your initial question.

Installing another Th350 would be far easier.
