4L80E 6-Pinion Planetary Sets (1991-96 2.75 1st/1.57 2nd Gear Ratios)
One of the most critical elements of any GM street/strip or towing application is acceleration.With that in mind, drivetrain engineers at TCI® recently designed two new 6-pinion planetarysets for 4L80E transmissions that provide powerful launches and improved gear transitions.Available in 2.75 1st/1.57 2nd or 2.97 1st/1.57 2nd gear ratios, these kits can release the trueperformance potential of your engine, whether at the strip or pulling a trailer, by increasing takeoffpower by 10 and 17 percent, respectively.

With a 6-pinion rear and 5-pinion front planetary, as well as heavy-duty CNC-machined billetconstruction, these planetary sets increase load capacity by as much as 17 percent, thereby givingGM performance enthusiasts more drivetrain durability in the long run. In addition, the lower 1stand 2nd gear ratios significantly increase take-off power for better all-around performance andimprove the rpm drop of the engine between gears. Simply put, the TCI® 4L80E 6-PinionPlanetary Sets will unleash the performance potential of any GM 4L80E-equipped street or dragracing application.

A perfect combination of durability and street/strip performance, these planetary sets are idealfor any GM performance enthusiast looking to improve acceleration right off the line.
