Two problems related to manual transmission have been reported for the 1997 GMC Sonoma. The most recently reported issues are listed below.
We have a 1997 GMC Sonoma with a votrec 4. 3 x. Over 2 years ago, we started getting misfires. We tried everything we could think of, to no avail. In the past month I've put over $500 alone. I have been looking it up on-line, and have realized, I'm not the only one with this issue. There has even been a recall in California, but only there. Gm told me they have different gas out there. Another major safety issue has been the wiper motor failure, that had a recall. Gm told me my VIN # was not on the list, but I battle my wipers at least once a month. I have to yank the blades half way up the window before they grab and start to work. One more problem that I now know I am not alone on is the issue with dex-cool. We have flushed and refilled the system at least three times, only to have it gunk-up again. Please help me and all the other customers who got trapped with junk vehicles. We have had too many other failures to count!.
Consumer states that while drivng and trying to change gears the rpm will rev up. Contacted dealer.
