Getting seals and internal components seated correctly during a transmission rebuild depends on having the right assembly lubricant, and this green assembly gel is formulated to stay where you put it through the entire assembly process. Unlike thinner fluids that migrate off surfaces, the gel consistency holds on seals, clutch pistons, and bore surfaces so every part goes in with adequate lubrication from the first moment the unit fires.
This is a single 1 lb container, universal fit, meaning it does not ship pre-matched to a specific transmission family. Technicians rebuilding a wide range of automatic transmission units use it as a general-purpose assembly aid. The green tint is functional, not cosmetic: it lets you see exactly which surfaces have been coated before you torque the case closed, catching any missed spots before they become a problem.
What is not in this package: seals, gaskets, clutch discs, steels, Automatic Transmission Filters, or any other rebuild components. This is the lubricant only. If your rebuild requires those parts, they need to be sourced separately.
Before ordering, cross-reference the listed assembly lubricant specification for the seals and friction materials in the unit you are rebuilding. Some seal compounds have compatibility restrictions with certain lubricant bases, and confirming that ahead of time avoids a costly redo. Weight is 1 lb as shipped.
