Don't know the ratio of the OD, but I know that it is a strong tranny for an OD. I've put over 400 (rwhp) at one and it's still in great shape. I like them. r
Strong enough to handle my Olds 455 with well over 500 ft lbs torque no problem. The OD is .70 I believe
I would like to know this as well. I like the size of the 200 and the gear ratios better than the 700. What mods were done to make it stronger or are you running them stock?
did some quick research. http://www.hemmings.com/mus/stories/2006/01/01/hmn_feature9.html 1981-'88 Buick LeSabre and Electra RWD 1981 Century 1981-'87 Regal 1981-'90 Cadillac Fleetwood, Deville and Brougham 1982-'90 Chevrolet Impala and Caprice 1981-'88 Chevelle, Monte Carlo, Malibu and El Camino 1984-'87 GMC Caballero 1982-'90 Olds Delta 88, 98 and Custom Cruiser 1983-'88 Olds Cutlass 4-4-2 and Supreme 1983-'89 Pontiac Bonneville, Parisienne and Safari Wagon 1981 Pontiac Firebird with 301 1984-'87 Pontiac Grand Prix Shift ratios for this transmission: 1st 2.74:1; 2nd 1.57:1; 3rd 1.00:1; 4th 0.67:1
I like mine in my 60 Corvette but it shifts from 1 to 2 way to soon under normal accellaration, been told to change governor but what do I change to?
Like the 700R4 you want a donor that is 1987 or later for a build these had the lubrication upgrades the earlier versions lacked.
A friend of mine "Scott McClay Engineering", builds the three speed version for drag racing. The first three gear sections of the 4R are the same as the three spd. version, and Scott's got them behind 900hp Super Stock car engines. The main difference between the 3 spd. and the 4 spd. version is the fourth gear. He'll also build the 4spd. version. So all that said, "first gear" thru "third gear" will hold up to just about anything. Just don't putting all 900hp into overdrive. It's for cruzin..! I've got two of Scott's overdrive transmissions, both have trans. brakes in them..! Art Carr (SoCal) is another good outlet. Plus he's got great looken office help that drives a Nostalgia Nitro Dragster. Art builds three versions, depending on the HP of your engine/car weight. http://www.scottmcclayengineering.com/ http://www.cpttransmission.com/ Mike P.s. - As you may know, the T-200-4R has much better gear ratios thAn the T-700.
I ran one behind a 377ci (De-stroked 400) that was a monster of an engine. Zero complaints here and it suffered many burnouts and rough driving. The 1-2 shift always sucked in mine as well but the horsepower made up for it
This has been debated many times.... The 200r4 was put in lighter cars. Smaller planetary gear ect.... Its not a bad tranny, but Not for me. Cheaper to build a 700r4 for sure. good lookin truck if the red ones yours
Cruising like that will get the ladies attention! Problem is you can't really get a look at them when you zip by.
Adjusting the TV cable in or out changes the shift points. Shorten it one or two serrations and road test
PML offers a great line of automatic transmission cast aluminum oil pans, some with additional capacity. http://www.yourcovers.com/transmission_pans.html Art Carr has the parts needed to convert the TH200-R4 to a non-lockup unit.
The 200 was a light duty trans. I blew one up back in the day over about 40,000 miles of abuse - in a stock Buick with the Olds block 307 in it. But part of that came from running it hot too many times. The 87-89 version may be better as noted.
