Planning your 8HP purchase
8HP is a family designation. Provide the complete identification from the original unit; different variants, engines and drivetrains require their own fitment and controls check.
Confirm my application with Big 3Dodge & Ram 8HP Transmission Replacement & Rebuild Options
Start an 8HP inquiry with the full transmission variant and vehicle VIN. Compare Dodge, Ram, Chrysler and Jeep catalog matches, then confirm the exact assembly and repair scope with Big 3.
Identify the transmission before choosing a product
Model name, trim and engine displacement are starting details. They do not establish transmission interchange. Send the VIN, model year, engine code, 2WD/4WD configuration and a photo of the original transmission identification label.
These guides cover selected families. If your transmission code is different or unknown, request identification help; the absence of a guide or catalog match does not mean the assembly cannot be supplied.
Replacement or rebuild?
Compare the exact supplied replacement with rebuilding your existing unit. Ask what inspection and work are included, whether the converter is supplied, and what the selected written warranty covers.
Plan the installation
Include the diagnosis, cooling-system inspection, fluids, transferred parts and programming in the installer discussion. Confirm any required supporting work and warranty conditions before the unit is installed.
Confirm the delivered total
Catalog prices are for the listed product. Some ship-first offers include a disclosed refundable core deposit; other core/exchange terms are quoted for the selected product. Confirm freight, tax and installation. Multiple assemblies or mixed freight require a shipping quote.
Current catalog options
These are catalog product-name matches, not a verified vehicle fitment list. Open the listing for the exact application, assembly, availability and written warranty. Product prices exclude separately quoted core deposits and order-specific charges.
