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).

It doesn’t stop leaks from the pee pad.
Size: X-Large: 28" x 34"
I’m trying to figure out how not to have leaks occasionally. I’m going to call the company to see if there’s something I should be doing.

FANTASTIC PAD HOLDER
Size: 28'' X 34'', Size: 28'' X 34''
Amazon Basics Dog Training Pad Holder 28X34. I'll start out by saying I wasn't too sure about it, when I got it. It is awkward to put the pads in by yourself if your short as on each end the sides have to come up together and it’s big, however, I've done it five times alone now and it’s doable. There was no smell, it arrived in perfect condition. My husband was home and we set it up together, I walked into the bathroom to get a soiled pad I had keep to put on it for her to know what to do came back and she had already used it and she’s only four months old. I love it love it love it, it’s not too big, but it’s her home too, and we have it in the living room where we spend a lot of time as we’re retired. When she gets a little older, we will probably move it to another room, but for now it’s staying there. After she urinates, it goes down to a very pale yellow color I have been able to use one pad for all day, however, she does have a pad in a under bed tote in our master bathroom. We’ve had a few guests over and if she hadn’t used it they didn’t even know what it was. I highly recommend it. I have been using pads in an under the bed tote for over 10 years and this is a welcome audition. You won’t be sorry if you have little ones that go in the house.

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!

Don’t buy
Size: 28'' X 34''
Mine arrived broken and scratched I think I received one that someone had returned. It also doesn’t hold pads that well my 4 lb teacup Yorkie is able to pull the pad off of the pad holder without even ripping the pad.
