Blind
I'm Awesome
5 people in the truck, went up the grade by my house into the next city, going 70mph, it downshifted to 3rd, then began to free rev until ~4k rpm, then 2nd gear hit. As soon as it tried to shift out of 2nd into 3rd again, it free rev's.
Had the truck towed home, tranny fluid was below the stick, I added 2 qts to get the level up on the stick again. There's a sound similar to a knock while running now, which I can mainly hear from the drivers side. It drives normally until it tries to shift to 3rd, which just feels like neutral, 4th doesn't work either. But 1st / 2nd the truck drives exactly like before.
`96 tahoe, 4l60e, 115k miles, I replaced both heads/rockers/lifters/pushrods last year.
I scanned for codes, and there are none.
The truck does have a hypertech power programmer on it, with shift firmness enabled.
Time to pull the trans? What broke?
