Shift pointers: Tricky sensor situations

Sometimes you’re the windshield and sometimes you’re the bug—a phrase many of us have heard and experienced. It’s inevitable. The idea is to be the windshield as much as possible. Shane from Cottman Transmissions had a helluva day but in the end, he was the windshield. In his shop he had a 2016 Explorer using

Honda Accord BB7A six-speed: P2720 code set after collision

The complaint A 2015 Honda Accord with a 3.5-liter engine and the BB7A six-speed transmission (seen in figure 1, above), was involved in a minor collision to the left front of the vehicle. The vehicle was drivable and was taken to the transmission shop. Vehicle diagnostics revealed a P2720 “Pressure Control Solenoid D Voltage Low”

Dorman introduces new torque converter solenoid for Subaru

Among new products released by Dorman is an OE FIX torque converter lock-up solenoid (part no. 926-408) that the company says is designed to match the fit and function of the original part on almost four million 2012-2020 Subaru vehicles. This new repair solution allows the replacement of just the failed solenoid rather than the

Watch: Clearing up common misconceptions about the Chrysler 62TE

In the latest video from the Transtar Garage Studio, Dave Hritsko, Transtar’s technical product specialist, talks about the Chrysler 62TE transmission. According to Dave, there’s one aspect of the electrical side of things on this transmission that has resulted in some common misconceptions: the solenoid on the valve body. Learn more in the video above.

Chrysler RFE Transmission Family Part 2: Solenoid and Valve Body Components

To enhance fuel economy Chrysler released the A500/A518 overdrives in the late ’80s and ’90s.

Kia Borrego: A5SR2 Transmission

This A5SR2 came into the shop in 4th gear failsafe. The codes pulled were P0732, P0733 and P0734 gear ratio codes along with a P0763 Direct Clutch (D/C) solenoid performance code.

Diagnosing Solenoid Performance Faults in A761, AB60 & A960 6-Speed Units

The Toyota/Lexus A761, AB60 and A960 6-speed transmissions have been showing up in shops more frequently over the last couple of years. Warranties are expiring and people seem to be hanging on to their vehicles longer these days. Even so, there are a number of different issues with these transmissions, including torque-converter clutch failure that is especially chronic with AB60 Tundra applications. Common to all these units is a problem that sticks out a bit more than the others, though: on-off solenoid mechanical fault codes. You’ll see these as P0751 S1 solenoid performance, P0756 S2 solenoid performance, P0761 S3 solenoid performance and P0766 S4 solenoid performance codes.

Double Trouble

In today’s world of automatic transmissions we see several different types of solenoids being used depending on the strategy the engineer chose to employ. There are the typical on/off solenoids that could be normally closed or normally open. And then there are PWM solenoids, normally applied or normally vented.

RAV4’s Transmission Dilemma Presents Challenge

The code chart for the P0770 shift-solenoid-E malfunction has a simple description of the diagnostic trouble code (DTC) checking condition: It says that the lockup does not occur during lockup range (50 mph) or lockup remains on during lockup-off range. The possible causes listed are that the shift-solenoid valve is stuck open or closed, the valve body is blocked or stuck, or the clutch is locked up.

Clearing up Some Toyota Solenoid Confusion

Different terminology for the same part has been an ongoing problem in the transmission industry ever since I can remember. When I was learning to rebuild transmissions, Chrysler Torqueflite and Ford C-4 transmissions were always in the shop. These two transmissions had the same power flow, but all the internal components had different names.
