i have a 96 k2500 pickup with a 6.5 and 4l80e. im having problems with reverse and possibly third gear.
reverse seems to be slipping. when i shift into reverse, it acts almost normal and starts moving rearwards, but if i give it some throttle it seems to slip for a short while and then suddenly grabs.
the other issue is the 2-3 shift seems to be very slow, or maybe third is slipping during shifting. its a bit hard to tell, as it wont shift until i hit 3500rpm, which is more or less max rpm on my engine it seems. it feels more or less like the shift itself takes too long, and maybe happens a bit late in the rpm range? im not sure..
for a while i suspected the reverse servo piston might be cracked, but then third shouldnt be acting up...? from what i understand, reverse and third share the same clutch, so thats possibly on its last legs?
but, is there any obvious, easy stuff i should try as a last resort before giving up and sending the transmission away for a rebuild?
