It's been a busy few months rebuilding Allison transmissions. With suppliers being behind and trouble getting certain parts and clutches in a timely matter. We have been doing the best we can. Have a bad a few trucks come in that the customer had just changed u joints doing them incorrectly or using cheap parts. Only spicer non greaseable joints get installed here to prevent thousands in damages when driveline vibrations break tail housings, bellhousings and adapter plate housings.

Please don't be a darwin and drive your truck until it doesn't move anymore and then some ps my hurting nose, headache and stinky shop for the next 3 days was not in my best interest today. Severely burnt synthetic fluid smells horrible, so bad we had to tear down this 6spd Allison outside!. If you do find your self with problems with your Allison transmission call/text/ message to get it built or rebuilt to withstand years of abuse. 712-579-4159
