Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
sounds like he gave you a junk tranny to replace the junk tranny... the pcm would not cause this
you said the fluid was burnt correct, when a trans neutrals out its a pressure loss from internal failure
burnt fluid is from burnt clutch and steels
as do most ....most people think changing oil is good maintenance , I would say either the band is burned or you have a leaking or damaged accumulator for 2nd or a damaged second gear servo or seal.
can you manually shift into 2nd or third? has it ever hit second? have you checked line pressure?
and was 2nd there? and was this a one time thing?
is the speedometer working?
check shift solenoid b wiring if they are good ill stick with my internal failure answer..
ok,,, start with checking B
