As cars keep aging, what will the future look like?
We always talk about the average age of a vehicle crossing the 12-year mark. But, I think the more interesting number is the average age of a vehicle that is scrapped. This is a difficult number to obtain due to title laws in the different states, but it has been estimated by some at 22
TCM trouble and the importance of being certain about parts replacement
It’s a tale as old as time. A vehicle comes in and, despite having been recently repaired by another shop, the vehicle owner’s concern is still present. In the case of this story, the vehicle came from a local shop we work closely with. The truck in question is a 66,000-mile 2006 Chevrolet Silverado 2500

2023 State of the Powertrain Industry
The Transmission Digest Annual Survey of Retail Shops has served as benchmark and planning tool for the industry now for the past 37 years. Charts and tables in this study are based on a survey that was conducted early this year. Where differences are obvious, we separate the responses of transmission specialty shops from general
Powertrain industry directory and buyer’s guide 2023
This is the latest in TD’s annual series of directories for the powertrain industry. Companies that supply products to the powertrain aftermarket are listed in alphabetical order.

Shift Pointers: No ball, no reverse
Yoram Levy from Israel gave us a call with a 2022 Chevrolet Traverse using a 9T65 that suddenly lost reverse. He had found a check ball missing in his valve body which he points out in figure 1 (above). Figure 2, below, shows how bad the plate was where this ball passed through. GM usually
The multi-functional Clutch 1 in Nissan’s CVT, part 1
Nissan’s Hybrid RE0F02/3H CVT transmission by Jatco (JF019E) can be found in vehicles such as the Nissan Rogue and Pathfinder as well as the Infiniti QX60. It has its traction motor located where the torque converter would normally be (as you can see in Figures 1, at the top of the page, and 2, below).

Scope testing the Ford 10R80
Recently, we at Certified Transmission had a chance to do some work with the Ford 10R80. We have easy access to test vehicles since our owner also owns a used car dealership. For our R&D testing we used a 2019 F-150 equipped with a 5.0L engine and the 10R80 transmission. I got to play around
Announcing the winners of the Top 20 Products and Tools contest

Shift pointers: A 4T65-E that wants to move in Park and Neutral
When conducting ATSG seminars, as we are usually covering a specific piece of tech, we’ll often tell attendees that if they put this together wrong, they should let us know what happens. Just recently, Ricky Hodgkinson from AACTION Transmission did just that. He was kind enough to share an incident he recently had with a
