Reproduction 1970-1971 Corvette TCS transmission switch. Correct for manual transmission equipped Corvettes. Includes "pin" type electrical connection. Switch threads into the transmission providing electrical signal for TCS solenoid on intake manifold.

GM Part 3961567

Transmission Controlled Spark (TCS) System controls exhaust emissions by eliminating vacuum advance in the lower forward gears while at operating temperature. The TCS intake manifold solenoid controls vacuum to the distributor's vacuum advance unit. The solenoid determines when, and how much, vacuum to release. Typically, a vacuum line from the carburetor enters the solenoid and another vacuum line exits the solenoid to the distributor vacuum advance unit (some applications have multiple inlet and outlet lines). The TCS solenoid relies on an electrical signal provided by other TCS system switches/senders via an electrical connection on the back or side of the solenoid (Engine Harness or TCS Harness plugs into this connection).

Dog Loves It, But Durability/Safety Major Issue
Size: 8 Inch, Color: Tree Branch
My 9 month old Frenchie loves it, but she got pretty sick this weekend and was vomiting all day...next day she finally threw up a big chunk of this toy...just beware if your dog is a heavy chewer, this may not be the right fit for you. Not the best durability...

She loves them, therefore I love them too
Size: 5.5 Inch, Color: Ring Toy
My furbaby LOVES these, especially the peanut butter flavored ones. I still regularly brush her teefers, but these do help with dental care.

Made mostly of POLYPROPYLENE PLASTIC and should not be injested.
Size: 8 Inch - 2 Pack, Color: Tree Branch
BAD PRODUCT. DO NOT BUY THESE FOR YOUR DOG. They are made mostly of POLYPROPYLENE PLASTIC. It even says on the package - "CAUTION: Product is not intended to be eaten or ingested. If you believe your pet has swallowed a piece, please take away and contact veterinarian if needed. Our dachshund went to town on one of these and had diarrhea for two days and cost us several hundred dollars in vet bills to do x-rays and medicine for the poor dog. What do you think a dog is going to do with a dog chew? Just find another product. This one isn't worth it.

It'll only last a week
Size: 5 Inch, Color: Classic Bone, Size: 5 Inch, Color: Classic Bone
We've only had it a few days and she's already half way through it. It won't last the week. She doesn't eat it, she spits out the pieces. If you buy it was a consumable, totally worth the money. I'll probably buy my power chewer a couple a month
