Transmission Replacement & Rebuild
When a transmission is genuinely beyond repair, you want it done once — replaced or rebuilt correctly and backed by a warranty, not patched until it strands you again.
Signs you may need transmission replacement
A transmission replacement is one of the biggest repair bills a vehicle can hand you, so the first thing we do is make sure you actually need one. Plenty of "you need a new transmission" quotes turn out to be a solenoid, a valve body, or burnt fluid. We diagnose and road-test before we ever talk about pulling it — and if a smaller repair will fix it, that's what we'll tell you.
When replacement really is the answer
Sometimes the damage is done — metal in the pan, a spun bearing, a burnt clutch pack, or a converter that's let go. When a transmission is genuinely finished, we walk you through the real options: a quality rebuild, a remanufactured unit, or a new one, with the trade-offs in cost and warranty laid out plainly so you can choose with your eyes open.
Rebuilt, remanufactured, or new — explained
A rebuild reuses your case and good internals with new wear parts. A remanufactured unit is brought back to factory spec on a bench, often with updated parts and a strong warranty. A new unit is exactly that. Which one makes sense depends on your vehicle, your mileage, and how long you plan to keep it — and you'll get a firm written quote before any work starts.
Diesel and tow-rig transmissions
If you run a diesel or tow heavy, the transmission is often the weak link, and a replacement that isn't set up for the heat will fail the same way the last one did. As an authorized BD Diesel dealer, we can replace or build an Allison, 68RFE, or TorqShift to handle real load — with the cooler and service schedule to keep it alive. We replace it once, set up to survive the work you actually do.
Transmission Replacement — common questions
Should I rebuild or replace my transmission?
It depends on the vehicle, the mileage, and the failure. A rebuild can be the better value on a truck you're keeping; a remanufactured or new unit can mean a stronger warranty and faster turnaround. We lay out the real options and costs so you can decide — no pressure either way.
How much does a transmission replacement cost?
It varies widely by vehicle and by whether you go rebuilt, remanufactured, or new — so we won't throw out a random number. We diagnose first, then give you a firm written quote before any work begins, with no surprises added later.
Do you warranty the work?
Yes. The unit and our labor are backed by a warranty; the exact term depends on which transmission and option you choose. We'll spell out the coverage in writing with your quote — call and we'll go over it.
Is it worth replacing the transmission on an older vehicle?
Often, yes — a sound vehicle with a fresh transmission can be far cheaper than buying a newer truck, especially with diesels. We'll give you a straight take on whether the rest of the vehicle justifies the investment before you spend it.
