#7 of 25 95 GMC Jimmy Auto Transmission Problems by gmcrich Jul 02, 2007 (9:11 am)
I have a Jimmy W/140K miles and it started acting like it was slipping/jerking ONLY when I was in reverse and heavy on the throttle. I changed the filter and made things worse. Now it only seems to have 2nd gear (40mph)and still jerks when I am in reverse. Prior to changing the filter I didn't have any issues with forward gears. I had a hard time squeezing the pan in and out of the exhaust. Could I have damaged or unhooked something by rubbing the pan across it? If I can regain my forward gears I could get by for awhile. Any ideas on what could cause these problems? Any help? Replies to this message: repairdog (Jul 03, 2007 3:07 am) gmcrich (Jul 03, 2007 6:16 am) repairdog (Jul 03, 2007 1:05 pm)

Replying to: gmcrich (Jul 02, 2007 9:11 am) You probably hit the wiing running thru beneath the valve body and may have nicked it or disconnected a solenoid. Replies to this message: gmcrich (Jul 03, 2007 6:16 am) repairdog (Jul 03, 2007 1:05 pm)

Replying to: repairdog (Jul 03, 2007 3:07 am) Is there a way of checking this through the computer codes? Does Autozone or Advanced Auto have a diagnostic machine for transmissions? How many solenoids are there and what do they look like? I just need to regain all of my forward gears and hope reverse lasts for awhile.

Replying to: gmcrich (Jul 03, 2007 6:16 am) Auto stores don't scan transmissions. Each gear shift has a solenoid. Most trans shops will hook up their scanner and give an estimate for free or low cost to get the business.

Replying to: ajw121 (Sep 14, 2006 1:26 pm) There is a major problem in the electronic controlled transmissions in the blazer. A simple way to get results is to pull the positive battery cable for 5 mins and then reattach it. That seems to reset the computer and fix the problem, but usually for only about 6 months.

#14 of 25 messed up tranny and ignition by churchillbilly Jan 14, 2009 (1:48 pm)
i have a 97 gmc blazer which has had the selenoids replaced once. it fixed the problem for about 6 months then the key started sticking in the ignition, problem comes back plus the battery keeps draining. i can start it cold and it will go for about 100 yds then the radiator gets hot and it shuts of however my electrical keeps working and the check engine light comes on, diagnostics said selenoid problem but i cant help but believe the faulty ignition switch has a big part to play any suggestions?

Replying to: fatboy7 (Mar 02, 2009 3:12 pm) can anyone tell me what a vacuum switch for differential does?   Are you referring to a differential pressure sensor? Those are used to detect pressure differences between one part of a system and another as in oil or transmission filtration systems.   tidester, host SUVs and Smart Shopper
