Overview:

The B&M® Transpak is the next step up from the B&M Shift Improver kit. It has all the features in the Shift Improver kit, plus it provides additional driver manual control (GM TH-400, 350, Ford C-6 and Chrysler Torqueflite only). The B&M Transpak™ for 1970-1982 Ford, Lincoln, Mercury C4 automatic transmissions recalibrate's your C4 transmission for optimum performance to best suit your needs. Most stock automatic transmissions won't downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you're in. With the Transpak, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when you've got a modified engine, and you want additional RPMs, or you're towing a trailer or driving heavy loads downhill. Stage 1. Heavy Duty is for street rods, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort and offers normal automatic operation when in Drive. Stage 2 is for Dual purpose performance vehicles, Hi-Performance Street/Strip, Off-Road/desert and 4-wheel drive use. Stage 3 - Competition use Only. Not for Street use.

Features:

  • Recalibrates your C4 Automatic Transmission
  • Full Manual Control on Most Transmissions
  • Improves Transmission Life
  • Optimum Performance
  • Firmer Shifts

Comfortable and easy to set up
Color: Black, Color: Black
I’m happy with this chair. It was not hard to assemble, and it feels stable after putting everything together. The mesh back is comfortable and breathable, so it doesn’t feel too hot when sitting for a while. The seat cushion is also thicker than I expected and feels soft enough for daily use. I like the adjustable headrest and the back support, especially for working at a desk. The chair looks simple and clean, and the wheels move smoothly. Good value for a home office chair.

very ergonomic
Color: Deep Black, Color: Deep Black
I bought this as a replacement for one of those gaming chairs that kills your back with a little lumbar pillow and this one is muuuuch better. the back support is everything you’d need and got rid of my neck pain after long periods of sitting and the seat cushion is supportive but still comfortable. It’s the kind of chair that you don’t really think about much because it’s so natural to sit in that you forget it’s there. The armrests flipping is a really nice feature too. One star off only because the head rest is so far back that i can’t really rest my head on it and every part of the chair that’s cloth is made of the same mesh texture like the armrests and seat. but i have no other complaints this is a good chair

Comfortable Ergonomic Chair for Long Workdays
Color: Black, Color: Black
I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.
