Not about anything for sale, but this did catch my eye & thought that it would be worth sharing.
There's GMT400 probs listed that I never knew of, let alone considered when purchasing or even when maintaining.
I think that most of the recalls have probably timed-out out by now, but along with the known trouble spots, this kinda stuff should be on a semi-regular maintenance check-list for all 400 owners or potential purchasers.
Could save a lot of time & $$$ instead of chasing unknown gremlins.
For some reason, 88/89 trucks aren't included in the list.
TROUBLE SPOTS
Automatic transmission
Description: Trucks with the 6.5L engine may have a transmission shudder when the torque-converter clutch applies and releases. (1991-94) |
Automatic transmission
Description: 700-R4 automatic transmissions may shift late or not upshift at all. The problem is a stuck throttle valve inside the transmission. (1990-92) |
Brake wear
Description: Vehicle pull or premature front brake pad wear, may be corrected with revised rear brake shoes. (1992-98) |
Clutch
Description: A grinding noise during clutch engagement and difficulty shifting into first or reverse is caused by a clutch master cylinder pushrod that is too long. (1992-93) |
Cruise control
Description: The cruise control cuts out and won’t reset unless the key is turned off because the cruise control module is too sensitive to vibrations at the brake pedal. (1994-95) |
Engine knock
Description: Engine knock at startup on 4.3-, 5.7-, or 7.4-liter engines is usually eliminated by using an oil filter with a check valve. If this does not fix it, GM has revised PROMs for the computers and will even replace the main bearings if all else fails. (1990-95) |
Engine misfire
Description: Damaged injection pump or lift pump on 6.5-liter diesel may clog the fuel filter. (1994-98) |
Engine noise
Description: The exhaust valves on 4.3-, 5.0-, or 5.7-liter engines may not get enough lubrication causing a variety of noises. Usually, the same engine consumes excess oil because the valve-guide seals on the exhaust valves are bad and have to be replaced. (1996) |
