Toyota’s K313 Continuously Variable Transmission
In 2014, Toyota introduced the K313 Continuously Variable Transmission in their 1.8L Corollas vehicles. It utilizes a torque converter eliminating a forward or reverse clutch-release strategy when in gear at a complete stop. The torque converter neck is a double-ear drive design that indexes into the inner pump gear.
Know Your Outcome
A couple weeks ago The Reman Runner talked me into doing a 5K: a race that happened to be a trail course, something I had never done before and certainly wasn’t training for. I convinced myself the three miles without any sort of recent running would be completely fine despite the total lack of preparation. Easy.
Extra Set of Eyes Saves the Day
In addition to the OEM-spec remanufactured transmissions we build, we also offer a series of heavy-duty transmissions available in three different stages. This article examines the installation of our Road Ripper™ 3000 (stage 3 unit) in a 2005 Dodge 2500 pickup equipped with a 5.9L diesel and a 618/48RE transmission. The vehicle had been in use for about a month when the customer returned with an issue that the transmission was stuck in gear and would not shift. We did not want any damage to occur by the customer driving the vehicle to our location, so we set up a tow to have the vehicle picked up.
Do unto Others
I believe the most significant management skill is the ability to deal effectively with customers, coworkers and suppliers. If you can continually treat all three groups with the respect they deserve just for being who they are there’s a good chance they will respond in kind. Customers will want to come to you because they know they will be well treated. Techs will want to work with and for you because you make them feel safe in their environment, and suppliers will want to go out of their way to help you because you don’t try to chisel them on every deal.

Get the Clip Instead of Getting Clipped
The pump shaft on a Subaru transmission is keyed to the converter and held into place with an inner circlip. Those who are familiar with this know to carefully pull the converter far enough out to clear the shaft from the transmission.
Replacing Valve Bodies Dos and Don’ts!
When you replace the valve body instead of rebuilding it, on one hand you gain by getting a valve body that has been refurbished with oversized valves, remanufactured or new solenoids, and tested to ensure it is working as designed. On the other hand, you don’t get the benefit of taking the original valve body apart to vacuum test bores, assess wear or find sticking valves or solenoids, and disintegrated checkballs and so on. You may even miss a host of other useful hints that can help explain why the transmission had the symptoms it came in with.
Programming: A Blessing or a Curse
To answer the question in the headline, we need to look at the programming of modules. Not the actual program, but the foundation on which it is based on.
Your Attitude Defines You
I often wonder how many people in our business are content with the trade they’ve chosen and are excited or at least happy about going to work each day. I know there are some, but I fear not as many as should be. After all, this is a very tough business. It’s one of the few that the job isn’t over when it’s finished. It isn’t over till the warranty has expired and for maybe some time after that.
Programming Can Be a Source of Profit
For those of you who perform J2534 programming, you may have noticed that there have not been any updates to the Ford Module Programming (FMP) since the last release of FMP 105. Although it had remained functional as long as your subscription was current (or at least up until the writing of this), it won’t be long before you will have to start using the new software that is labeled as FJDS (Ford J2534 Diagnostic Software).
