I’ve been having a really frustrating issue with my 4L60E transmission lately. It just won’t shift into second gear, and it’s causing a lot of headaches. I’m hoping someone here has experienced this before or has some insight into what might be going wrong.
Symptoms
The transmission shifts fine from first to third.
There’s a noticeable delay or no engagement at all when trying to shift into second gear.
Occasionally, I hear some strange noises when the car is struggling to shift.
What I’ve Tried
I’ve checked the transmission fluid, and it seems to be at the right level. No signs of burning or discoloration either.
I performed a basic reset of the transmission control module hoping it might recalibrate or something.
I’ve done a visual inspection for any obvious leaks, but everything looks good under there.
Possible Causes?
I’ve read a bit online, and it looks like there could be several things at play here, such as:
Solenoid issues: Maybe the second gear solenoid is faulty or stuck?
Valve body problems: Is it possible that there’s a blockage or wear in the valve body that’s affecting the shift?
Mechanical failure: Could this be a sign of bigger mechanical issues inside the transmission?
Seeking Your Expertise
If anyone here has dealt with a similar issue, I would love to hear your suggestions or diagnoses. Do you have any things I should try checking? Would it be worth taking it to a professional, or is this something I might be able to troubleshoot myself?
I’ve had similar issues with my 4L60E transmission. Loss of second gear can often be attributed to problems in the valve body or low fluid levels. Have you checked your transmission fluid lately?
Check to see if the governor is stuck or has worn components. You can also test its function with a pressure gauge! It’s fairly straightforward once you get into it.
I think it’s also crucial to monitor those fluid levels closely. Too low or dirty fluid can cause erratic shifting. Just a friendly reminder for everyone!
I can help you with diagnosing the lack of second gear in your 4L60E. First, check for any error codes using an OBD-II scanner. This can point you in the right direction.
If you’re comfortable, try checking the internal wiring within the transmission. Some people find frayed wires causing all sorts of odd shifting behavior.
