If you’re lucky, your thoughts, opinions, and ideas are challenged every day. Regular, open discussion is a healthy thing, especially when it comes to justifying what you’re most passionate about.
But let’s be real. With the various responsibilities you have in your day and how busy work can seem, it’s easy to fall into a consistent, comfortable, unchallenged rut.
With vehicles staying on the roads longer than ever before, we’re seeing more age-related issues with our customers’ cars. With age comes the increasing probability for human intervention in the form of aftermarket alarms, stereos and exterior lighting. A recent multi-hour, hide-and-seek experience with a 1992 Acura Vigor simply underscored this fact.
Tech-support hotlines have been burning up for years with phone calls concerning rapid gear-train failure in GM TH400 transmissions after routine rebuild or repair. It’s time to address the issues that cause this and reverse widespread confusion surrounding gear-train setup on this and similar units. Today we will clear up the mystery in setting proper endplay for this transmission. If tolerances are not set correctly, costly comebacks can result.
Understanding these basic checks on the 400 will give you back-ground knowledge in setting build procedures that will be used with similar gear sets, such as 4L80-E.
Although Hyundai was not the first manufacturer to offer a six-speed automatic transmission, they ultimately made up for lost time. In 2009 the car company released a series of six-speed transmissions to accommodate a wide range of Hyundai and Kia applications. The transmissions can be FWD or AWD and are rather compact in design. There are three basic levels or sizes that can overlap vehicle models and engine displacements.
I am sure everyone in our industry is familiar with Tremec, one of the world’s largest and technically advanced manual transmission manufacturers. For years Tremec manufactured 3- and 4-speed transmissions for Ford, including RUG, RAT, SROD, RUG, TOD, etc. Tremec acquired the manual transmission division of BorgWarner and then produced the T5, T45, 3650, T56, TKO, and the TR6060. Manual transmissions have been on a steady decline on vehicles manufactured in this country for years and are now confined mainly to sport or performance models.
Occasionally you will have a vehicle come into your shop that takes you down a different path than what you might have expected. The following account tells the story of one of the times that it happened to me. The star of this show is a 2006 Chevrolet Silverado 2500 4×4, equipped with a Duramax diesel engine and an Allison 1000 transmission.
Paying bills is one of the most difficult things we have to do in business for a number of reasons. One that always bothered me was that the money I worked so hard to get didn’t even have a chance to get all warm and comfortable in my checking account before I had to take it out to pay bills. The old “hard-come, easy-go” scenario. It was almost like the money was never really there. Time is another factor. The time it takes to pay bills pulls you away from money-making activities, and we all know that’s where we should be placing most of our energy. Of course some of us have bookkeepers to help with the bill paying, but often we need to get involved anyway to determine who needs to get paid now, who can wait longer, and how much we can pay each creditor.

Manual transmissions are in a continuing decline in volume. Most current manual transmissions in domestic vehicles are relegated to the sports or “muscle-car” segments of the market. Of the “Big Three” domestic manufacturers, only Ram options a manual trans for purchase; Ford and GM do not. Part of this decline is a lack of skill and talent in the driver population, who are used to automatic transmissions so that nothing interrupts their ability to text while driving. The EPA does not like stick transmissions because they cannot control the throttle opening during operation.
In the transmission business, overlooked driveline problems are a cause of comebacks that are not related to your build but can still hurt a shop’s reputation. Making some basic checks of the vehicle while it’s still in the shop can get ahead of many driveline-related issues and help reduce comebacks.

If I encounter a sales rep who even remotely sounds like he’s trying to feed me B.S., I’ll take my money elsewhere – simple as that. Once trust in the individual is broken, it makes you question the honesty of the company – and products.
