The answer depends on your motor, your vehicle weight, application and your pocket book. Each model has a higher horsepower and torque rating. SOmeones going to move this to the tranmission section Im sure, but a turbo 400 is a 3 speed.There are several versions of the 700R4 transmission, including heavy-duty, super-duty, and Xtreme SS models. In 1993, the transmission’s hydraulic shifting system was replaced with electronic controls for the 4L60E version. In 1990, General Motors changed the name of the 700R4 to 4L60, which represented 4-speed, longitudinal, 6,000-pound gross vehicle weight rating. Overheating can also cause a warped valve body, which can be problematic when changing gears. Slipping between 3rd-and 4th gears can occur when overheating weakens the metal of the clutch-pack disks, causing a problem with the clutch-pack that engages those gears. Overheating is another common issue, though it can be avoided by installing an auxiliary transmission cooler. My original plan was to put in the 6.0L LQ4 & a 700R4 trans that. backed by a monster 454 big block engine with a 700R4 transmission. If thats not high enough, then trim down the weights or use lighter springs. The standard v8 governor is only good to about 4000 to 4500 wot shift points. The transmission has several common problems, including a broken 27-spline input shaft in early versions of the 700R4 (after 1987, 30-spline shafts were developed to improve the reliability of the gearbox). I throwing together a swap for my 84 Monte Carlo SS & Im trying to choose a transmission. a max gross takeoff weight of 600 kilograms (1,323 pounds) or 650 kg (1,433 lbs). brandon706 2 yes, but try the 'corvette governor' first, that should be a good starting point of around 5500 to 6000 wot shift points. Most of the unit’s internal components are shared with the ’93-later 4L60-E, which was regularly improved/revised up through. It also became a popular upgrade for older rear-wheel-drive General Motors vehicles. Introduced in 1982, the 4-speed Overdrive GM 700-R4 transmission also known as the 4L60 remains a popular option for street/strip performance applications. The 700R4 was GM's overdrive four-speed replacement for the three-speed Turbo350. Elsewhere in this story we’ve listed the ratios of both the TH350 and the 700R4/4L60E. The good news is that either way, you win. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4. The transmission was designed for trucks and large cars but is compatible with a variety of Chevrolet, GMC, Cadillac, Pontiac, Buick, and Holden vehicles between 19. If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. Type of vehicles, Rear-wheel drive, Heavy Engine Cars Overdrive, Overdrive, No Overdrive Weight (without fluid), 155 pounds, 135 Pounds Gear Ratio, First. It is a four-speed automatic transmission with overdrive and was introduced as a way to make V8-powered cars and trucks more efficient. Sungear shaft reduces friction & increases longevity. Upgraded 3-4 clutches increase torque capacity & clutch life. 300M input shaft allows for higher torque capacity. The only other hurdle was replacing the large Turbo 400 slip-yoke with a slightly longer CPT slip-yoke to make up for the fact that the 200-4R is roughly 11/16 inch shorter than the TH400.The General Motors 700R4 transmission was manufactured by Chevrolet in 1981 to run with 1982 model year vehicles. The TCI Super StreetFighter GM 700R4 Transmission is designed for higher horsepower and higher torque street/strip applications. But because we had already moved the crossmember in our Chevelle to mount the TH400, the crossmember bolted back in with zero drama. The important point is that the 200-4R places the trans mount farther back than either a Powerglide or a TH350. The transmission case lengths do vary slightly between these transmissions, but even that's not a deal breaker. What makes the 200-4R such a great choice is that it will bolt right in place of a TH350, Powerglide, or, in our case, a TH400. We started with one of CPT's performance transmissions treated to all the good mods. '09 issue, we showed you why a 200-4R is an excellent choice for an overdrive automatic, as well as the modifications that California Performance Transmissions goes through to make these boxes even stronger.
