My father-in-law and his next door neighbor both own 99 Silverados. My
father-in-law's transmission recently went out at 42K miles and his
neighbor's went out about a year ago around 56K miles. They both required a
complete tranmission replacement and they both got rebuilts.
I own a 01 Suburban (my first Chevy) with similar drive train and this has
got me a little spooked. Are these incidents just a rare coincidence or are
there inherent tranny problems with these models?
I have a 2002 silverado 1500HD 4l80e tranny
This transmission is starting to fail again for th 3rd time.
Truck has 34000 km on it.
GM will not replace any transmission in Canada if they can get you
past the warranty period at minimal cost to them.
I believe GM transmission failure is a far greater problem than anyone
If they are past warranty, find a GOOD tranny shop and have them
rebuild it properly. My experience with GM and their service tech. has
not been very good to say the least.
Too bad we do not have any consumer laws in CANADA to protect us.
If this happened down south in certain states GM would be having this
truck back in the re-cycle bin.
If you were stuck with one of these things within GM warranty, would you do the
preventative cure or try to totally fry it to get a complete replacement?
I did the sleeve thing figuring they'd just stick me with another flawed design.
What is considered pricey? I am expecting 2k for a complete R&R. I
have an '00 Silverado 1500 Z71 extended cab with 65k on her. I don't
notice any hard shifts when warmed up. All of my hard shifts are when
cold and no codes are set as of yet. I am wondering to do the
preventative maintenance or just wait till she pukes. I do have the
GMAC extended warranty and am good for 10k more, but like you said, I
am sure they will just hand me another grenade. What's your opinion?
FYI: Also, I never tow and only hauled a couple of dirtbikes in the
bed (800lbs max) is all I have ever done. I have the trans fluid
changed every 15k as per yours and Gary's advice, but I still don't
have the aux cooler as of yet.
Thanks for the info!
IIRC, the G-man does the Sonnax valve-sleeve for under half of what a
complete rebuild would cost. Sorry I can't remember the exact dollar
figure; I know it's no more than a grand.
If you pay close attention and have your PCM scanned regularly, you can
catch the P1870 before the AT grenades. If you catch it as soon as it
happens you're good to go and won't need an entire transmission.
I have a "99 Tahoe 4x4, 4dr, LS. My trannie went out at 60K. Cost 2 grand
to completely rebuild. I cound send ya a parts list of the goods that had
to go in it if ya'd like. It's basically the same trannie that goes in all
their 5.7 rides, from Z28 (1988) to Suburban (2004). I'm not sure how they
expect the same trannie to move a truck 3 times the weight of the Z.
btw i had to have the Z28 IROC's (1988) rebuilt but that was probably owner
