Transmission..next step HELP
1997 Chevy Blazer 4.3 4x4 automatic. Had the typical solenoid issues when bought. I replaced all solenoids and wiring harness inside. Cleared all codes and drove off. 10 minutes later ALL codes returned, stuck in the 2-3 mode. Had my friend clear all codes with a Snap On brick and drove it again. 15 min. later all codes, and stuck in 2-3 again. The solenoids were all new and wiring was also. Pan was clean. I am at a loss. Also, key sometimes sticks. I am pulling my hair out trying to understand this. All solenoids fit snug with no looseness. When it works it works perfectly. I cleared the codes this morning and then unhooked the battery, drove it 30 minutes before it did it again. Could the ignition switch or the neutral safety switch be doing this to it? I just can't believe it is the solenoids again. :icon_hyper:

Getting any codes? Jerry

Sounds like it could be the ignition switch. Have you tried to monitor the power to the solenoids through the 'trans' fuse?
|
It throws codes. My scanner says what the code means so I didn't write the codes down but, TCC solenoid, shift solenoid A, shift solenoid B, etc..
How would I monotor thru the fuse? |
From my experience, thinking you've got some 700 codes-the ignition switch is looking like the odds on favorite. Jerry

Getting one tomorrow. I have to believe it is that. The key hanging up, all NEW solenoids and harness, new fluid and filter.....Just seems the way to go.

Connect a multimeter to a suitable ground and then connect the positive lead to either side of the trans fuse, leaving the trans fuse installed. Then drive it. You should have +12V in run.

DC Voltage... :icon_doh: |
