1st off i`m new to here. i am in the z28.com club too. i just got this blazer. the other day for 400.00 the tranny seems to be bad or something. drops in to gear really good pulls from 1 real hard but when shifting to any gears it slips. 1 to 2 slips 2 to 3 slips 3 to 4 seems like its no going into 4. didnt know if the shift soleniods are bad or it just needs a rebuild. can get it rebuilt for 550.00 from this guy i know. he is really good and has done a 4l60e for me in my 94 camaro. which is a 383 bye the way i built it. any input would be helpful.

 

Slipping in everything but 1st sure sounds like the trans is spent.
