An RE7R01B Dilemma
Harold Grisham from Grisham Transmission Center had quite a dilemma on his hands. A 2016 Nissan Titan comes to his shop with a sudden no reverse with 60K on the odometer. This vehicle has the RE7R01B transmission in it and this is where the dilemma begins. After a basic inspection, it revealed the ATF level
Diagnostics vs. Repair Roles
Being relatively new to transmission diagnostics, I’m always learning new techniques to try and simplify the process. However, at times it still can be overwhelming. After my years as a reman plant worker and R&R technician, I find there is more of a mechanical approach in the transmission repair field compared to the electrical side
Diagnosis: Do the Homework
Occasionally in diagnosing transmission problems technicians are faced with challenges that force us to look beyond the transmission control system. As vehicles become increasingly complex, it is crucial that we educate ourselves with all systems pertaining to the vehicle we are diagnosing. Many systems are tied together in one way or another and can directly
The State of the Converter Industry
With all things considered; I think we had more business problems in the market crash of 2008, but we overcame that situation, and I believe we will all survive this ordeal.

Trouble in Reverse
When I first started the engine, the car jerked and moved forward 5’ and then neutralized. I noted a hydraulic pump whine also, and when I brought it into the shop I first checked the fluid and found transmission. This Mustang had 96,000 miles on it, so I thought surely this wasn’t a serious electrical issue.
Wiggle the Wires
Acouple of months ago we had a customer come into our location with a 2006 Kia Spectra equipped with the 2.0L engine and an A4CF2 transmission. The customer’s concern was that the vehicle would not shift at times. I started the evaluation by checking all the fluids, doing a visual inspection, and conducting a battery and charging system test with the Midtronics analyzer, and everything checked out good. I then moved on to connecting the scan tool to the vehicle and checking all modules for DTCs; the only one that came back was a P0748 (linear solenoid) electrical problem. There was no freeze frame data stored; it probably wouldn’t have helped me with this issue, but I wanted to see if it would at least show the speed or temperature at which the code set. From the customer’s description it sounded like an intermittent issue.
That’s a New One
