never said it didn't have two stalls. you can't compare your newer chevy to a older one. nothing about them is the same. i have a th-400 and 208 combo and have had no problems yet. the 700r4's were never intended to be used off-road. stay away from them unless you are gonna be driving the truck more on the street.

Again wrong here. Nothing wrong with a 700R4. The only thing wrong with them is nut behind wheel that does not gear axles properly with them. I have seen some 700R4's take a terrible beating and live as long as they were not driven on stall a lot under heavy load and not properly cooled. There is a few company out there that offer 700R4 rated at 700 HP and warranted to do it too. It is arguably one of the best trannies GM ever made and has a lot of potential when properly used and built. 4 gears is ALWAYS better than 3.....

if you want the over drive. as in street driving. there is also companies that build th-400 that can take over 2,000 horse power. i have never met anyone that like the 700r4 execept you. to get the 700r4 to handle that amount of power you have to spend a small fortune on it.

also why did gm never put a 700r4 in a one ton truck? it was never intended for heavy duty use. it was designed for better gas mileage.

How did we get to 2000 HP?? The reason you do not understand them is because you are really stuck on the OD thing. See I do not look at a 700R4 as a OD tranny but rather a 4 speed tranny. If you take you sacred THM 400 and use it with your favorite gears, 4.10, you have a lowest gear ratio in first of 4.10 x 2.48 or about 10.2 to 1 which sucks for a big lifted 4x4 in high range. Now take a 700R4 with 5.38's and you have 5.38 x 3.06 or about 16.5 to one, a BIG change and we are still in high range. In reverse the 400 combo has a 4.10 x 2.07 or about a slug like 8.5 to one (gonna need a lot of torque converter action to back up with any serious load or in soft ground) With the above 700R4 combo you have 5.38 x 2.29 or about 12.3 to 1 (about 20% deeper than first in 400 combo) In top gear with 400 combo you have 4.10 x 1 x 1.07 (non locking torque converter slippage) or about 4.38 RPM wise. With 700R4 combo you have 5.38 x .7 or about 3.77. Heck even with a 6.14 gear ratio you would only have a 4.3 effective gear ratio in top gear with 700R4 combo (and a 6.14 would be about the same overall ratio in second as thm 400 in first. See it is all about gears and as long as you do not look at a 700R4 as a 4 speed tranny but rather a OD tranny you will never see the real potential here.Want give 700R4 a bad name is people that gear trucks to tall and slow bakes them in forth gear riding converter. (and 700R4 with much deeper first gear is gonna launch better with same axle ratio than a THM400 and in a way it is its own undoing because it makes some think it is okay.

we got to 2,000 hp because your trying to talk up some little 700r4. i don't think you understand what i am trying to say. your the one that is stuck on the 4.10 gear thing not me. i have never said that they were my favorite gear ratio. a 700r4 is an overdrive transmission not a four speed. its a three speed with an over drive. even when i have seen a 700r4 in a truck that is set up properly it still doesn't live because its still a half ton transmission.

See what I mean, you are stuck still in OD mode here. It is a 4 speed tranny and it is called OD because top gear is taller than 1 to 1. See you fail to realize that is is a 4 speed box and whether 4th acts like OD when used (ie low rpm) depends on axle ratios. Guys like you make me chuckle because they want a bad 4x4 yet they handicapp them with taller gears to run old tech 3 speed boxes rather than gearing them deep and using a 4 speed box. Your axles are your strongest reduction units in your 4x4 by far. With a 4 speed and a 700R4 I consider 4.88 with 35's fairly good combo (5.13 is you play hard) as 4.56 with 33's (4.88 if you play hard) not 3.73's which either which many do and blame tranny. If I was running 38's it would be at least 5.38's. But see many like you simply do not see the potential of a 4 speed auto IF you gear it properly and are stuck in a old way of thinking. You are going to have a heart attack if you have to use a 6L90 one day because it has no drive gear range (1 to 1) 4 gears under drive and to gears "OD". ALso many front wheel drive cars have had "OD" trannies for years even before they were called that because tip gear was like .97 or .89 or .92 and so on but they did not call it OD because it was "packaged" with a axle ratio that did not give it OD performance. Gear a 5x5 deep enough and OD will not really be OD any more but you cannot seem to grasp that ring.
