tranny has a strange screetching noise in only first hear manuely selected or in drive. was on alldata and a service bulletin said it the tc, tcc. also said replace tc or tranny.....way expensive theres gata be less expensive and or invasive fix... anyone else had the same prob???

 

Cheap, Fast, Reliable are a few words that come to my head pick 2 cause it's not going to be all 3.

 

I hear a "whine" in mine that simply sounds like gear lash.

 

is it a 80 or a 60? our 2500 has 6.0 with a 4l60e and it has wine in first aswell sorta sounds like streaight cut gears
