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 1965-1987 GM TH400/375 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.
Features:
- Recalibrate's GM TH400 Automatic Transmissions
- Full Manual Control on Most Transmissions
- Over 65 Years of B&M Quality

An Absolute NEED In My Skincare Routine!!
Pattern Name: 50 count (1 pack of 50 ct), Pattern Name: 50 count (1 pack of 50 ct)
These are an absolute need in my skincare routine! I use them to remove oil-based and water-based cleansers and to remove masks. And I use them to dry my face and then to dry my hands in between products. They are very good quality and very soft. They are also thick and very durable. They have a smoother side and a textured side for very gentle exfoliation. I notice my face is more clear from using these as opposed to my microfiber washcloths. They’re fragrance-free and don’t really have a scent, maybe a very light, practically unnoticeable, bamboo scent. I think it’s a very good deal to get 50 XL disposable face towels for $17. I was using these for months and then didn’t use them for a few months and yeah huge difference in my skin, which is why I bought them again and will continue to. It’s also great not having to wash them lol! I also love the new magnetic lid closure and the new design of the box, you can now have your face towels fully covered and sealed without having to buy a separate box with lid to put them in. Although their prism holographic box is so cute and pretty, and their prism box is $20 cheaper on Amazon!

Great quality face cloths with a soft exfoliating texture to them.
Pattern Name: 50 count (1 pack of 50 ct)
Absolutely love these towels. So nice to have a clean towel every time you wash your face. They are the perfect texture for lightly exfoliating. These are just dry towels so you can use your own face wash with them. They are very durable. I tried ripping one in half once and was unable to. They are quite large and I have found that I can have twice as many by cutting them in half. They are still a great size after cutting them. I can definitely see why they are so highly rated. I definitely wasn't holding my breath with high hopes but after using them I am pleasantly surprised! They are quite reasonably priced especially if you cut them in half and if you subscribe to them for additional savings. Very surprised how much I love them!

SOOOO GOOD
Pattern Name: 50 count (1 pack of 50 ct)
I finally caved and bought these. I wish I would have hoped on this trend when it was first talked about in the skincare community because they are SO good, soft but also exfoliating, no scent, perfect for your face or anything else you want to clean.
I did get the XL size without noticing but I’ll be buying these regularly.
It makes doing my skincare at night so much easier.

Strong, but soft on your face

They are nice and strong, they don’t tear. It is nice having a clean cloth to wash your face with.

💙 The Secret to a Cleaner Face & Clearer Skin
Pattern Name: 50 count (1 pack of 50 ct), Pattern Name: 50 count (1 pack of 50 ct)
“I’ve been using these Clean Skin Club Clean Towels and I really like them! They’re soft, durable, and feel much cleaner than using the same face towel repeatedly. They’re gentle on my skin, don’t cause irritation, and are great for drying my face after washing. I also love that they’re disposable and help keep bacteria away from my skincare routine. Definitely a great addition for anyone with sensitive or acne-prone skin. Highly recommend! 💙🧴”
