Trany guys, help, a few ?? stock 4l60 ----->
Friend has a 05 tahoe, 5.3 with 72k on it 100% stone stock.. Just out of no where yesterday he says it will not shift out of 2nd.. Today, i go take a look. Fluid is fine, not burnt. I take the truck for a ride, manual shift the trans, will not shift out of 2nd. I then repeat this with the to haul on, it went into 3rd 3-4 times. After trying to get it to do it again and it would not.. What could it be?? When it did shift into 3rd, then OD it was fine, no slipping or noises.. So if this has happened to ya or you heard of this, drop a line in here.. I have a few ideas, but not sure what to go with :/

ive heard something about a transmission safe mode but from what i hear about that it stays in one gear and WILL NOT shift at all so it doesnt sound like thats his problem... other than that i dont have a clue but g/l with it. if it comes down to it and he needs a replacement my stock 65e is up for sale! only 25-30k miles on it since it had a fresh rebuild when i bought it.

Yes I am pretty sure it made it to 4th one time.. So from a stop, 1st would shift fine, then shift to second fine, then it would just stay in second. Only when I used the tow haul button did it go into 3rd, almost sure 4th 1 time..
