Frequently Asked Questions
How do I confirm the TH400 Promod Billet Aluminum Direct Drum Kit w/ 36 Element Sprag fits my transmission?
Match the exact transmission family, case, year or generation, input and output interfaces, dimensions, hydraulic or electrical strategy, and manufacturer part number.
Are supporting parts included?
Only the exact component and hardware expressly listed are included. Gaskets, seals, fittings, fluid, wiring, fasteners, and related transmission parts may be separate.
Is professional installation recommended?
Yes. Transmission and converter work affects hydraulic pressure, rotating assemblies, driveline alignment, cooling, and safety. Use a qualified transmission technician.
Installation Instructions
Confirm the exact FTI part number and complete drivetrain specification. Disconnect the battery and support the vehicle safely. Follow FTI's current instructions and the vehicle service procedure for converter seating, clearances, fasteners, fluid, cooler lines, wiring, linkage, driveshaft, and initial fill. Verify converter-to-flexplate clearance before tightening. Check fluid level at the specified temperature, inspect for leaks and abnormal noise, and recheck operation before full-load use.
