1991 GMC Sonoma SLX 4.3 V6 gasoline
Summary:
Fun to drive with great handling and power!
Faults:
Usual maintenance. Replaced front end components in 2016.
Electronic ignition module seems to "time out" and must be replaced periodically.
In really hot weather, the throttle body injection system can get vapour lock, making it harder to restart.
Had to replace an axle in the rear due to cracking on the splines and excessive wear.
Rear fenders can be especially susceptible to rust.
General Comments:
Features a Geitrag 5 speed transmission (same as on BMWs) with a Hurst Shifter package.
When I obtained the truck, the transmission was exceedingly noisy. Seems the first models needed some buffer between the 4.3 and the transmission to prevent "burning out" the front end of the transmission. With a little research, I determined there was a "secret" warranty to fix this problem. I took the truck to a local dealer to approve the fix and ended up with a new transmission with the fix! No cost to myself except the time!
Despite the mileage, it is a strong performer with decent fuel mileage. I have beat Porsches off the stop line at intersections and can be several hundred yards ahead of the pack before others catch up to me. Gotta obey those speed limits!
Did a partial restoration on the body couple years ago to bring it back like new. Used a polyurethane jet black paint to give it a deep as a pond like finish. Run BF Goodrich truck radials on American Racing rims.
My mechanic describes it as a "pretty little truck" with lots of attitude! It is a single cab, bucket seats, long box with posi differential and era correct aluminum cap over the box.
Hope to start exhibiting it in car shows soon, now that it is over 25 years old. It is a keeper for sure.
Easy to keep this one on the road as parts, OEM, aftermarket, and used are plentiful and cheap since so many were produced and are seemingly still popular.
The small truck market where I reside is strong with few ever on the market, and the vehicles themselves commanding a good price due to desired acquisition.
Would you buy another car from this manufacturer? Yes
