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

Won't last a day
Color: Blue, Color: Blue
My 50 lb. Pitt bull destroyed this chew toy in 15 minutes. One week later. I'm changing my rating from a one to a five. My girl spent up until now ripping it apart and pulling the stuffing and squeaker out. She had so much fun that I bought her another one. When I took it out of the box for her, she was so happy, she immediately tried to tear it apart.

Lasted 2 minutes
Color: Grey, Color: Grey
Gave it a 2 star bc it was cute and on time. I have a GSD- a mildly aggressive chewer. This toy literally lasted 2 minutes and there was stuffing coming out so I had to take it away. Wish I would have read the reviews before I purchased.

Only Made It Two Weeks
Color: Grey, Color: Grey
This toy easily became my Fig's favorite toy. The squeaker wasn't as annoying as it is in many other dog plushies. However, that's where the positives end. After the first week, there was a hole in the stitching on its neck. I sewed it up, but it obviously did not last. The squeaker went silent after a few more days. I bought it on March 28th, and it is now April 12th. It's just a rag, now. RIP little honey badger. You did well in your short life time.

Not 100% indestructible, but cute and worth the money
Color: Grey, Color: Grey
My dog absolutely love this little toy although when I looked up indestructible dog toys, this is one of the first things came up. I have to say it is not indestructible. I have not found one single dog ball or chew baby that is indestructible. My dog has found every which way to destroy them. It is now four days later and it’s still almost intact, but she has placed a hole in it. It does come with a squeaker, although the second day she already pulled it out it’s cute and it’s fun. Your cat could technically play with it if you had a cat and they wanted one quality wise, I would say it’s definitely close to indestructible, but it’s not completely indestructible and the colors were so fun.

It's not indestructible.
Color: Blue
Buyers beware, I have a jack russell, and I just got this item ten minutes ago, my dog ripped it up.It is not indestructible, it is a waste of money. My dog is very aggressive with his toys. So back to the drawing board...So I can't return this item because, it's ripped up and they're not gonna give me my money back... So do not buy this toy.
