Product Overview
The Zumbrota Remanufactured Manual Transmissions RMT56D-1 is a replacement 6-speed manual transmission designed for compatible vehicles that require a professionally remanufactured drivetrain solution. It is built for buyers who want dependable manual transmission performance backed by careful inspection, clean housing preparation, tested internal components, and fitment support before ordering.
This unit is identified by Manufacturer’s Part Number RMT56D-1, Summit Racing Part Number ZUD-RMT56D-1, and UPC 883584304319. These product identifiers help vehicle owners, mechanics, repair shops, fleet maintenance teams, service departments, and drivetrain specialists confirm the correct replacement transmission before purchase.
The transmission features a 6-speed configuration and an aluminum case. These specifications are important for buyers replacing a compatible manual transmission and planning the correct drivetrain installation.
The bellhousing is not included, the yoke is not included, and the shifter is not included, so these supporting components should be confirmed separately before installation.
For the best ordering experience, have the VIN number ready. VIN-based fitment support helps confirm compatibility and gives buyers more confidence before purchase.
Fitment and Application Details
The Zumbrota RMT56D-1 remanufactured manual transmission should be matched carefully to the intended vehicle before ordering. Manual transmission fitment can vary by vehicle year, engine, drivetrain, original transmission code, clutch setup, bellhousing style, shifter configuration, speedometer arrangement, and driveline layout.
Important fitment details to confirm include the vehicle’s VIN number, year, make, model, engine, drivetrain, original transmission identification, bellhousing compatibility, clutch disc setup, flywheel, pilot bearing, clutch release system, output yoke, driveshaft length, transmission mount, crossmember position, shifter setup, speedometer requirements, and fluid specifications.
The bellhousing is not included, so the correct bellhousing should be confirmed before installation. In compatible applications, the original bellhousing may be reused if it matches the intended engine and clutch system and remains in proper working condition.
The yoke is not included, so the correct output connection should be selected separately.
The shifter is not included, so the correct shifter assembly, linkage, handle, boot, and interior fitment should be confirmed before ordering.
For a complete installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, bellhousing, yoke, shifter parts, transmission mount, driveshaft components, fluid, seals, hardware, and vehicle-specific installation parts.
Build Quality and Reliability
The Zumbrota Remanufactured Manual Transmissions RMT56D-1 is built through a detailed remanufacturing process focused on inspection, cleaning, component verification, and replacement of common wear parts.
Each transmission receives a pre-inspection to check for case cracks, excessive wear, and OEM-related concerns commonly found in used transmission cores.
A second inspection is completed during the remanufacturing process to help confirm that component parts meet OEM specifications.
A final post-build inspection is performed to confirm that the finished unit meets strict quality standards before shipment.
Internal components receive 100 percent inspection, including gear wear checks, main shaft straightness testing, and synchronizer testing.
The remanufacturing process also includes 100 percent replacement of seals, bearings, and other common wear components, helping provide a dependable manual transmission ready for proper installation.
The housing and top covers are cleaned using a hydro-blasting and rinsing process, helping restore the case to a clean OEM-style finish.
Each unit is shipped in a high-density plastic tote to help protect the transmission during transit and reduce the risk of shipping damage.
