Transmission stories to be thankful for

Transmission repair is all about solutions. Problems present themselves; repair professionals solve them. That’s why this Thanksgiving, we’re thankful for solutions.

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?

Let’s find out!

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

The Chrysler 948TE has an offset pump mounted in a housing that is retained by round internal snap ring that must be squeezed to release the pump from the housing. The difficulty in doing so: there is a double tension plate located at the bottom side of the pump. Read Wayne Colonna’s story on how 3D printing helped solve this problem here:

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.

I thought to myself, there must be an easier way. It was when I was building a 4L60-E transmission that I discovered this easier way.

What did Rick find? Read on below.

4) The diagnostic value of the scope

A scope is a powerful diagnostic tool. Lately we have seen our share of ECMs and TCMs failing, and the following stories are examples of such computer failures and how using a scope in the diagnostic process helped determine the cause.

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.

Shift of the shaft: Diagnosing Chrysler 48RE manual shaft issues

The TorqueFlite transmission has been around since mid-to-late 1950s. There have been many changes surrounding the manual shaft and rooster comb through the years. This transmission shaft controls the position of the manual valve that directs oil for the gear ranges, but it also is used for a Reverse light control as well as Park/Neutral

The TorqueFlite transmission has been around since mid-to-late 1950s. There have been many changes surrounding the manual shaft and rooster comb through the years. This transmission shaft controls the position of the manual valve that directs oil for the gear ranges, but it also is used for a Reverse light control as well as Park/Neutral safety control. As it evolved, changes to these safety backup switches caused extra stress against the rooster comb that posed new challenges to the technician. 

Sometimes, a diagnostic code is all you need

With ATSG having the opportunity to help shops solve problems, sometimes we get faced with some real doozies. A shop will call and give us a laundry list of DTCs, leaving us to think someone must have a bulkhead connector unplugged. We then go through the arduous task of deciding which codes prompted other codes

10L80 and 10R80 pump gear differences

You may have seen an article in the August 2023 issue of Transmission Digest called “GM 10L80: A new kind of pump noise,” which goes over how the front cover housing in the 10L80 is fitted with a converter drive gear and idler gear. The idler gear drives the pump’s driven gear, and is press

Easy TH400, 4L80-E reverse servo setup: Craft your own tool

While not as sensitive as some shifting bands, the Reverse band adjustment on a TH400 or 4L80-E transmission is critical, and failure to get it right has tripped up even the best builders. There is nothing worse than getting the transmission installed, putting it in Reverse and then not going anywhere or having no engine
