I have played with a few auto trans in my time and the main drive system looks just like a C6. I know its a rule not to pull hard in overdrive but looking at my 4R100 planitaries on the bench, there is no difference in the size of the gear sets.

ABSOTUTLY.

Hey Toy, The key phrase in this thread is pulling with the T/C locked up. Thats like driving a stick. I have an overide on mine and I don't pull hard with it unlocked. Makes so much more heat unlocked.

Yup . . the ONLY time I have even close to a heat issue is when pulling up a BIG LONG hill with the TC unlocked. My wife made my climb up to skyline drive out in VA or W. VA this summer while pulling the camper. I could only hit 35mph on a good stretch and I was getting a bit nervous as I was right around 200-210 degree's. Luckily the beast made it to the top and had some time to cool off. I can't imagine what it'd be like going out to some of those campgrounds in CO that are up around 9-10,000 feet. Climbing up to the Eisenhower Tunnel is a piece of cake because you can keep your speed up and the TC locked, but some of those twisties into the National Parks would be tough!

Have a good one,
Dave

I think you could get by real well with a DP Tuner in a 40 or 50 hp tow setting. BUT, I would HIGHLY recommend an extra tranny cooler. They cost about $100 including installation at most tranny shops. Put it on in tandum with the stock one. The Transgo shift kit and new valve body is also a good idea. Switch to a synthetic tranny fluid and that will drop your temps as well. Cool tranny temps and firm shifts are the key to making your tranny live a long happy life. I can't go this far without also recommending an ATS ported turbo housing as it will also keep your turbo from going toast from surge. It will your egt's down as well.

Pappy19....Do you get a kick back from ITP/ATS or what? Almost every post I have read lately you're pimping product... /ubbthreads/images/graemlins/shrug.gif

The wicked wheel will fix the surge as well. For IIRC $65.00

To stay on topic, the 4R100 IMHO is a great trans if taken care of with maintenance and driving habits, I have 155,000 miles on mine and many of those miles are with a trailer in tow, and in most cases the truck has been making 80-100hp more than it came with from the factory....I've added a better TC and Sonnax/Springs and feel it shifts and pulls better than ever.

Good Luck, /ubbthreads/images/graemlins/warmsmile.gif

Some users of the WW get a little relief from surge and some get not much at all. The ATS takes care of 99% of surge and they get lower egt's. No, I don't get any kick back, I'm just trying to help fellow PSD owners from ruining their turbos. If that is bad, then I'm real sorry. Ask all those that have lost their turbos if they had spent that $450 on an ATS housing if they would like a little hind sight. Isn't Hamilton a subburb of Darby?

I have installed 4 WW's for friends with 99.5 and up 7.3L's and it cured the surge for them.....I'm glad you like to help people.... /ubbthreads/images/graemlins/smirk.gif I do too.

Hamilton is not a suburb. Darby is a small town 17 miles South of Hamilton on HWY 93.

The 4R100 is rated for 1000 ft lbs of torque (horsepower means nothing to the tranny in itself, although an increase in HP without an increase in engine peak RPM usually means more torque).

Anyway, 1000 lbt sounds like a lot and none of our engines produce that much, but thats what a torque conveter does - turns high input RPMs into higher torque output, so that actual torque being applied to the rest of your tranny is not easy math.

For what it's worth. the 5R100 is rated for 1100 ft lb. (the last 3 digits are the torque rating X 10.)

Most manual tranny's have a much lower rating (sometimes as little as half)

 

[project20v]

The 100 does mean 1000 ft lbs, but do you know if that rating is input or output torque??? Very different...

Im my opinion the 4r100 is a great tranny. If the engine is left stock the tranny holds up to constant severe use for around 150k miles. The problem is a weak convertor and soft shifts primarily designed for comfort... Upgrade those 2 and it becomes much better. When you jack up the power without upgrading the tranny it will almost certainely fail much earlier...

The rating is at the input shaft, which is after the torque converter multiplication.

Just remember that 1000 and 1100 torque figure includes the torque multiplication factor or anywhere from 1.8 to over 2 depending on the TC for the lower gears. To no exceed the designed Ford specs on the tranny I think you can only safely add like between 45 and 75 HP before you're outside the design specs of the tranny.

I put 203,000 on my stocker 01 and 103,000 of those were with a Hypertech power Programmer III. Tranny was still good when I got the BTS!!

My 99.5 has 220k on it, never touched the tranny yet. its pulled plenty of loaded 5th wheel flatbeds, and it just has a 100hp chip, 4in pipe, and stg 1 intake. I am wondering if it would be safe to put stage 1 or 2 single shot injectors in it? i dont want to spend much on the tranny so what do you all think is safe?
