I experienced a P0708 code on my old 1997 Blazer 2 years ago, and it turned out to be a shift solenoid sensor which was faulty. It was a 50 dollar fix (at the dealer) and I never had the problem again. I remember when driving, it seemed as if it jumped when shifting gears (it was an automatic). try seeing the price on the shift solenoids (there are 2 if I remember correctly, the A, and the B). It's worth a shot. I took it in to pep boys before reading about that code and they told me the whole transmission was faulty, and it would cost 2000 dollars to fix. I fixed it for 50, so it's worth a shot to replace the solenoids first. (mine was the B solenoid)
