Transmission and Transfer Case modifications are becoming more and more common in the 4-wheel drive world. We not only offer professional rebuilding of transmissions and transfer cases, but we also carry factory replacement units ready to be installed. For the hard-core off road enthusiast, we offer many combinations of 4 and 5 speed manual and automatic transmissions. We also sell and install Ultra-low transfer case gear sets for most vehicles. We not only lower your gear ratios, but we also LOWER the amount of money you spend to get set up the way you desire.

Remember: The slower you are able to traverse an obstacle the more control you have, and the safer your 4-Wheeling adventures will be! Look for the best names here!

Whether your going up hill or down hill, having the correct gear for the terrain your driving is always a plus. Tanner can get you the best combination of differential gearing, t-case gearing , and transmission gearing for the type of wheeling you do.
