When an MT640 or MT643 unit comes off the vehicle and goes on the bench, the rebuild goes faster when all the wear-related components arrive together, and that is what this set is assembled to do. Unlike prepackaged kits sourced from a warehouse shelf, this one is put together at the REMCO facility by hand, piece by piece, and checked against its own parts list before it ships, so what you ordered is what lands on your bench.The set covers the core consumable categories for the MT640 and MT643 automatic transmission: seals, gaskets, friction plates, and steel plates. That combination addresses the clutch packs, the case sealing points, and the apply circuits in a single order. The shipped weight is 7 lb, which gives a useful reference when comparing to other sources to confirm you are receiving a full complement rather than a partial set.What this set does not include: Automatic Transmission Filter, band, thrust washers, or bushings. If your teardown reveals worn bushings or a damaged band, those need to be sourced separately. Knowing that before the unit is disassembled helps avoid the bench from sitting idle waiting on a back-order.MT640 and MT643 units have appeared across a long production span, and internal configuration details can differ between build dates. Before placing the order, locate the model code and build date stamped on the transmission case and confirm they match the MT640 or MT643 designation this set is built for. REMCO has been working with automatic transmission components since 1991, and the parts list included in the box lets the technician verify piece count at receiving rather than discovering a discrepancy mid-rebuild. Addresses the full range of wear points in MT640 and MT643 units by combining seals, gaskets, friction plates, and steel plates into one sourcing stop, reducing the risk of missing a critical component during teardown. This set does NOT include an Automatic Transmission Filter, band, or thrust washers. If your rebuild requires those components, source them separately before ordering to avoid delays on the bench. Friction plates and steel plates are counted together with the sealing components in a single shipment, so the technician is not cross-referencing multiple invoices when the unit is already open on the bench. Contents: friction plates, steel plates, seals, and gaskets covering the MT640 and MT643 rebuild. Shipped weight is 7 lb, which reflects a complete master overhaul complement for these units. Before ordering, confirm the exact transmission model code on the unit tag and verify the build date range; MT640 and MT643 share the same kit but internal configuration can vary, so match the code on the case before pulling parts.
