R&R Tech: 62TE transmission not shifting correctly
This article is in reference to a 2012 Chrysler Town & Country equipped with a 62TE transmission and 3.6L engine. While this might not be a technological breakthrough, this case is worthy of discussion as we have seen this issue on numerous occasions over the years. The transmission in this vehicle was one of our
When TCM gets cold feet
A couple months ago we had a customer contact us about a problem that he was having with his 2000 Nissan Frontier 4wd Pickup. While he had some trouble explaining the exact symptoms that were occurring, we understood that the problem only seemed to happen when it was driven first thing in the morning, and that in simple terms, “it just didn’t want to go.” We arranged an appointment for him to drop off the vehicle with us so we could perform our initial diagnosis and evaluation after the vehicle sat outside overnight.
Cause and Effect
A customer brought in his 1994 Toyota Camry, concerned that his brakes were hanging up as he was stopping. When I road-tested the vehicle I confirmed that there was a strange dragging feeling upon light brake application. I also noticed that when the brake pedal was applied, the “R” lamp in the PRNDL indicator illuminated even though the selector was in Drive. I also noted that the ‘tail lamp out’ warning indicator came on at the same time. The first obvious check was to take a look at the taillights themselves. I have learned over the years that you never ignore the signs right in front of you, even if you think they might be completely unrelated.
Don’t Overlook the Basics
Our carry-out customer was working with a 1999 Chevrolet Suburban 4WD equipped with a 4L60-E transmission. Their technician was able to re-create a slip/flare condition on the 2-3 shift. The fluid was full but a little burnt. A quick hookup of the scan tool revealed no codes existing in the system. Pressure gauges were attached for testing and indicated around 75 psi at idle, and 125 psi at the half throttle position.
