BD Diesel TowMaster Transmission & Converter Package (AS69RC) | Part# 1064274SS

Let’s be honest: when you’re driving a RAM 3500, 4500, or 5500, that AISIN AS69RC is the heartbeat of your truck. But when you’re running heavy loads daily, the factory setup isn't "bulletproof"—it’s just a transmission that’s doing its best until it isn't. We’ve had guys come into the shop with a thousand miles on their odometer and others with a hundred thousand, all dealing with the same "AS69RC fatigue." If you’re feeling that slip, or if you just want to stop looking at your transmission temp gauge every time you hit a steep grade, the BD Diesel TowMaster Package is the permanent fix.This isn't a "race" transmission that’s going to jerk your neck off at every stoplight. It’s a work-grade upgrade. BD Diesel took the time to figure out exactly where these units fail under commercial duty and reinforced those areas. When you bolt this in, you aren't just replacing a part—you’re upgrading your truck’s capability to do the job it was actually bought for.

Why we trust the TowMaster for AS69RC Builds:

• The Converter is the Key: The stock converter is where most of the heat comes from. BD’s upgraded converter locks up tighter than the factory unit. It transfers power more efficiently and, more importantly, keeps the heat out of your fluid.
• Reliability Under Load: These transmissions are built with upgraded clutch packs and internal components designed for high-torque, high-heat environments. It’s built for the guy who is actually working his truck, not just driving it.
• Consistency: You don't get the variable quality you’d get with a random rebuild at a local shop. Because this is a pre-tested, turn-key system, you know exactly what you’re putting in your truck.
• Perfect Integration: This is a "drop-in" package. No weird compatibility issues, no custom sensor work. It’s built to work with your RAM’s factory computer, so it’s ready to work the second it’s installed.

Common Shop Questions

"Is this worth it for a truck that isn't pulling max weight every day?"

If you have a 3500+ and you’re driving it for work, you know that "every day" can change in a heartbeat. If you’re towing a trailer for fun on the weekends or running heavy loads for your business, this package gives you the reliability to never have to worry about the drivetrain again. It’s an insurance policy for your sanity.

"Does it shift differently than the stock unit?"

It feels "tighter." You’ll notice the power feels more direct—less "mushy" and more responsive. It doesn't shift hard like a drag-race trans, but it shifts crisply.

"Why shouldn't I just have my current one rebuilt?"

A rebuild is only as good as the parts the shop can get that week and the skill of the guy doing it. BD Diesel is using their own proprietary parts that were designed specifically to fix the inherent flaws in the AS69RC. You get a higher floor of quality from the jump.
