Application: Street/Strip - Heavy Duty
B&M 20261 Shift Improver Kit
Fits 1988-1994, General Motors TH-400 (3L80)

Now you can get all the performance you've always wanted from your automatic transmission with a shift improver kit from B& M. You get two different levels of performance in one kit, heavy duty or street/strip.

Stage 1 is the heavy duty stage. It will give you firm and positive shifts without any loss of driver comfort. This is recommended for use in daily driven passenger vehicles if you are looking for overall improved performance.

Stage 2 is the street/strip stage. This stage delivers very positive shifts that are desirable for high performance street use and for competitive bracket racing on the strip. This stage will give the hardest, quickest possible shift.

The 20261 B&M shift improver kit is easy to install with just basic hand tools and an afternoon's time. This is the easiest and least expensive way to turn your transmission into a B & M tuned unit.


A B&M Shift Improver Kit is not a repair kit for an ailing transmission.
Your transmission must be in top condition before installing this kit.
