c0055 Code for vehicle speed sensor. I am getting fluttering speedometer and strange noises when accelerating. Engine runs fine at idle. Have replaced cv axles. Replaced output vehicle speed sensor on transfer case. Still throwing code and making strange noise. Gets worse in 4wd. Changed front and rear diff fluid. Neither was low. Drain and fill on transfer case. it was low. Engine and transmission fine. Just did engine oil and filter regular change. I have cleared the codes with an actron scanner 2 and after about 5 minutes of driving even at 30mph the c0055 comes back. Any ideas anyone? A u1300 code was originally thrown, which was resolved by cleaning ground wires that attach at chasis under drivers door. That hasnt come back.

The transfer case was low... but I am trying to chase the code down. The spot where the tcase is leaking is the usual culprits, the front and rear seals for the driveshafts. Not leaking terribly.... normal in my opinion for most older 4x4's. Anyway.... I need this fixed and I am weary of changing anymore parts, anyone have any experience with this? I hate to drop it off at the shop...

What I was getting at is if ran low on fluid, chain could be stretched, metal wear particles in fluid, etc etc could mess with sensor readings and thus code. Just a guess, could be hundred other things, wiring ,connections, etc. Need to get diagnostics and follow to isolate problem.

well you called it with a hole in the case. i looked it over before i bought it sure enough didnt see the patch job. the joker who had it before me put a pop rivet in it to seal the hole, but it had another worn spot in the case which made the seals for the shafts wobble. thus the leaking. impossible to find without a lift to see that damage. so now im on the hook for approximately 2900 as the quote from the dealer to just replace the entire transfer case. or about 1600 from a local guy to drop and swap the transfer case with a 12/12 warranty. this is in ocala, fl so if anybody knows a better deal let me know!

opinion of chevy is going downhill quick. i bought the truck with 99k miles on it. paid what i thought was an average price. not so much now.
