How to Build a TH200-4R for Drag Racing
Art Carr loves the 700-R4 overdrive automatic transmission as much as the next guy. The problem is, these transmissions blow up when they’re subjected to real power. That’s why Carr is a huge supporter of the TH200-4R overdrive automatic. Blessed by GM’s Hydramatic Division with superior guts, it only takes a few well-chosen tweaks to make a TH200-4R live behind as much as 1,000 horsepower. Got a 6-71 supercharged 468 rat motor in your daily driver—like Robbie Whitlock’s ’66 Chevelle? Carr can build you a TH200-4R that’ll take the gaff.
Swap in an Overdrive
If you took part in our first Power Tour or read our coverage in the September ’95 issue, you may remember this ’70 Plymouth GTX. It was one of the HOT ROD Tour vehicles that couldn’t complete the 2900-mile trip. While the Ford and Chevy guys might get a kick out of that, it should be noted that the car’s demise was caused by a cracked aftermarket torque converter—the only non-Mopar part of its drivetrain.
Bulletproofing a TH200-4R Automatic
When it comes to GM performance automatic overdrive transmissions, most discussions center around the TH700-R4. While this four-speed auto has its merits, the TH200-4R offers equal if not greater strength with a slightly different set of ratios. In fact, longtime transmission expert Art Carr believes the TH200-4R is potentially a far better performance automatic.
