1999 silverado 5.3 218,000+ miles 2nd gear is out

have the fault codes read to find out the servo/solenoid that is not working'
check that the vacuum actuator for the transmission is working and that the vacuum hose is connected
that is the unit that makes ratio changes possible at certain rpms and vacuum settings from accelerator pedal positions

rebuild or put a used trans in it they have hd zpack made for 3and 4 gear

If tranny fluid is clear and at normal level, then the issue is with the transmission - it is getting ready to go sayonara.

Better get that fix before you get stranded.

COULD BE THE GOVERNOR WORN OR DAMAGED.I WOULD HAVE IT TAKEN TO TRANSMISSION SHOP.HE CAN RUN A DIAGNOSTIC TEST USING A SPECIAL SCANNER TO CHECK 1 - 2 SHIFT SOLENOIDS AND 2 - 3 SOLENOIDS.ALSO YOU COULD BE HAVING PCM PROBLEMS.IT NOT CONTROLLING THE SHIFTS.

sound like its time for a new tranny, reverse goes first and the 2nd gear

Honestly a tranny flush, and new filter wouldn't hurt.

I have a 4x4 1999 Silverado K1500 with the 4.8L and had about 180,000 on it when I had the same problem start, after you get into 3rd and OD the problem quits right?

This is an educated guess, but you might want too have your garage checked out the worm gear, especailly if th truck has been used to pull trailers, or been in ana rea where there is slippery roads alot.

It seems Chevrolet had a problem, but no re-call, with the worm gears in that couple of years. The heavy use, and spinning of the tires on wet/snowy/icy roads broke off the spines on the gears.

Good luck, and I hope this helps you.

Bad news.....take your BIG check book to the garage, I paid over $1,000 to get mine repaired (and I know the guys really well).

change the fluid and filter if u havent already if that dont fix problem have trans. checked out u didnt say how many miles are on the vehicle?

if it is a automatic gearbox check the level off the gearbox oil if it is tho low it starts tho shift pritty hard

hello, your truck will not shift from second to third . If it wont shift to third it is going to need new clutchs or seals installed in the transmission that is a common problem with the 4L60e transmission.
