Here at TD, we pride ourselves on playing a role in getting transmission professionals the assistance they need, whether that’s technical info or just telling stories of industry successes. Here are five transmission stories, trends and tips we’re thankful for as Thanksgiving 2022 arrives.

1) How to get started with OE ECU reprogramming

The conversation goes like this: I have been paying mobile programmers or remote access programmers (RAPs) far too long. I believe I can save money and time by doing this myself. What type of equipment is needed and what is the cost to get up and running?

2) A 3D printing solution for 948TE offset pump access

3) An easier way to install the center support in GM transmissions

From contributor Rick Hodgkinson: Whether you are working on a 6L45, 50, 80 or 90, installing the center support that houses the L/R and 2-6 Brake clutches into the case can at times be difficult. In the past, I would grab the inside of the assembly with my fingertips on the friction teeth of the 2-6 clutch pack. I’d lift it up and bring it down into the case as perfectly as I could so it wouldn’t get cocked in the case. And if all went well, the L/R clutch would index and the assembly would slide right in. But then there were times when it needed to be jiggled around before it finally sat in place. By this time, I would have raw fingertips.

5) Ford 6R140: Repairing the elusive intermittent neutral condition

The 6R140 has been in large Ford trucks since 2011 and is now considered a common unit in most shops. Our discussion today concerns the elusive intermittent neutral condition. At one particular time, this complaint was so common at one particular California utility company with a fleet of trucks that there seemed to be no solution in sight.
