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). B&M® Transpak™ kit for 1980-1986 GM TH350C (Lockup) automatic transmissions. 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 Hi-Performance street use. Essentially the same as Heavy Duty mode except shifts are much quicker. Retains full automatic features and standard shift points with selector in Drive. Notes: Does Not Fit 1968-1980 GM TH350 (non-Lock-up) transmissions.

Features:

  • Recalibrate's GM TH350C Automatic Transmissions
  • Full Manual Control on Most Transmissions
  • Improves Transmission Life
  • Optimum Performance

Light weight, not thick or bulky, versatile, and perfect!
Color: White, Size: Small
Throw out all the tank tops you own cause this is the only tank top you will need from here on out. It is absolutely perfect. Let’s just say they understood the assignment. It is form fitting and pairs perfectly with lightweight sweaters that might be slightly sheer or even the new crochet type of open sweaters that need a tank underneath. It is the perfect stretch, perfect material and dressy enough to be worn on its own and upgraded with some jewelry and some classy jeans and has just enough sheen to look dressy and not like you’re wearing a workout top. I love , love this and it is my go to tank!

Comfortable, flattering wardrobe staple
Color: White, Size: Small, Color: White, Size: Small
I’ve tried a lot of basics, and this ANRABESS sleeveless scoop neck tank exceeded expectations. The fabric feels soft and breathable with a nice amount of stretch, and it has a flattering fit without being too tight or restrictive. The scoop neckline is classic and versatile, making it easy to layer or wear on its own. Stitching and construction appear well made, and it held up nicely after washing with no shrinking or loss of shape. Great quality for a basic essential, and a piece I can see reaching for often. Highly recommend.

The length is perfect. Nice and long.
Color: Yellow, Size: X-Large
These tanks are the perfect length. I love how they fit and feel. I bought these in 5 colors. Although, if you want to keep them long, I suggest hanging them to dry. Putting them in the dryer shrinks the length about 2 inches.

Great Tank Top
Color: White, Size: Large
I love this top. It fits snug and is comfortable. The length is perfect. I especially like the wide shoulder straps which hides my bra straps. I’ll order more of these in different colors.
