You’ll also notice the TV Cable coming from it. Be aware that the TH350 has 13 bolts, and a more square transmission pan. Owing to the fact that they have very similar dimensions, the 200-4R is often mistaken for the TH350. The 200-4R pan gets smaller toward the end, whereas the 700R4 is almost a perfect square. The pans look wildly different and will make identification a snap from here. At this point you should be confident that you are looking at either a 700R4 or a 200-4R. If you are able to count the pan bolts, it is far and away the easiest way to identify it.

Here is a good resource on how to perform that adjustment. If you are swapping into a vehicle that was not originally equipped with the 200-4R, make sure that your detent cable matches your throttle bracket, which should also match your carburetor or fuel injection.Īdjusting the TV Cable can be quite the challenge. These transmissions will wear out before they otherwise would if the cable is not properly adjusted. Many people have complained about the reliability of the 200-4R. It is very old and simple but tells you exactly what you need to know regarding adjustment and how exactly it works. Here is a great write-up on the TV cable and adjusting it. It involves pressing a half-moon looking button that changes the geometry between the transmission and throttle blade. Adjusting the TV cable is a relatively simple process. The TV cable serves as a combination of kick down cable and throttle position sensor. Sometimes it is referred to as the detent cable. The 200-4R Transmission uses a Throttle Valve or “TV” Cable just like the 700R4. Weight: Roughly 118 pounds with no torque converter or ATF It’s controlled by a TV Cable and a locking torque converter. Outer Case Material: Aluminum, fused with bellhousingĬontrolled by Computer: No. It’s main reason for existence at all was to fit into the engine bays of existing models that the 700R4 could not accommodate. The 200-4R really was not a necessary compliment to the 700R4. This allowed for further economy improvements. This allowed for no slipping of the transmission at highway speeds. They all came with locking torque converters. The best factory 200-4R transmissions can be found in the Monte Carlo SS and Oldsmobile 442 that were released in 19. This makes swapping it into a vintage muscle car even easier.
All 200-R4’s utilize a mechanical speedometer gear. As long as you go with someone reputable, the issue of these transmissions inherit effects have been ironed out for quite a long time. Just look at the torque capacity that they offer and go from there. Also, it’s a no brainer when it comes to aftermarket transmissions. But a 200-4R from the end of its production run is going to be a lot more dependable than an early 700R4 and vice versa. The 200-4R has a reputation as being the weaker of the 200-4R/700R4 siblings. It was produced with the usual Chevrolet bellhousing bolt pattern, but was also produced with the Buick, Oldsmobile, and Pontiac patterns as well. This allowed it to easily be used in vehicles designed with the TH350 in mind. The TH200-4R has the smaller footprint of the two, and is very similar in size to the TH350. The 200-4R is very similar to the 700R4, although there are some differences between the two of them. It is a the lesser known of the two overdrive transmissions made by GM in 1980’s, and is still considered part of the Turbo-Hydramatic series. The Trans Go SK-700 is a decent shift kit.The 200-4R is a transmission that was manufactured by General Motors for the 1981 model year. I prefer the Trailblazer SS Servo part# 24229159.Good compromise between the standard V8 servo & Corvette servo. I wouldn't spend a dime on it unless I completely rebuilt it.You just do not know what shape it is really in.Ĭorvette Servos are overrated, It provides greater clamping force on the 2-4 band.But also can create a overly harsh 1-2 shift. As always I really appreciate the info And I wouldn't be asking the questions if I haven't searched like crazy lol I see a lot of guys buying the vette servo but I'm not sure if I want to do that or not. If this one is good enough then all I think I need is a torque convertor with a 2200 stall and a shift kit. I sent the pics to a local transmission shop and they are always really busy but they said it was a 1990 but they couldbe just said that because they are so busy. Would this be a good enough transmission for a shift kit? and would it be good for my truck? It's a 85 c10 with a somewhat built 350.
