A little rubber seal seems insignificant and is easy to forget. In this case, Eric talks about how important this seal is on your brake calipers. Without it, dirt and debris clog up the caliper bolt bore; eventually leading to a seized caliper that prevents it from doing its job. All you 2011-2019 Duramax owners especially, look at your calipers. If you don't have these seals or they're in poor condition, you need to make sure you have them!

Would you guess this Duramax is 25 years old? Normally when we get a call about an LB7, we prepare for a truck that's been through it all and needs lots of repairs. In this case, Dennis was pleasantly surprised to see how good a condition this Duramax was in. All this customer needed was a routine inspection and an oil change. A Duramax from 2001 still going strong and looking as good as ever. Take good care of your truck and you may still have it 25 years later!

Anyone who's had an LB7 may be familiar with this hole in the intercooler piping. On the driver's side near the power steering line sits this intercooler pipe. If the ducts are not aligned correctly on either side, this pipe becomes shifted into a slightly wrong spot and begins to rub.
Eric points out the easy way to avoid this: Use the hash marks the way they're intended and line them up properly. It's so simple that it may be overlooked unintentionally, but ignoring this is not a risk that's willing to take.

This transmission from an LB7 that Dennis worked on 10 years ago came back in to us. This customer has had over 100 drag race passes with this truck on this trans. Joe was thrillled to see how good a condition everything was still in after a decade of drag racing.
Although it's finally time for an upgrade, 10 years out of this trans with that much stress put on it over the years is impressive. We set high expectations for ourselves on any truck we work on; we love to hear and see stories like this! How long have you been on your current transmission?

We've had a few months working out of 286 Hecdor at this point. Lots of stuff got done this summer and more will be done this fall. We've had lots of laughs along the way too; the personalities of everyone here haven't changed a bit. Especially Joe, who still needs to work on his uhhs and umms...

Protect your radiator from dents and scratches with the brand new Merchant Automotive Radiator Shield. Over 20 years ago, Eric had the idea of a cover for the radiator while working on the front of the engine. There's been make-shifts and prototypes created, but now we have a real-deal, sturdy, and well-manufactured radiator shield that fits any and all Duramax radiators.
Use as a magnetic shelf to store tools, bolts, flashlights, and more as well. Cover it in stickers, write on it, customize it however you'd like while keeping you radiator safe. The guys in our shop use our radiator shield, and now you can too! Give us a call or take a look today: https://www.merchant-automotive.com/ma-radiator-shield/

Joe talks about one less thing you need to worry about with your Allison transmission. You do not need to remove the converter to fill it with fluid. Once it starts up, the fluid and assembly l**e immediately start doing their job. Keep the converter seated and don't be afraid that things are running dry. Our Allison transmissions are designed and assembled to give you less to worry about.
