Since this tread seems to have been hijacked
Let's see if I can get this tread back on the subject of torque converters. We can all agree that a torque converter that is slipping as it is locking up creates heat. Too slow of a t.c. lock up or too much torque from the engine at the time of lock up will cause slipping before lock up. Which in turn damages the clutchs and the torque converter clutch pistons.

Stock torque converter clutch pistons are actually a very poor design as far as the material they build them out of. Which in turn makes them more prone to warping. And once they are warped they are going to keep creating heat and destroy the t.c. clutch friction material or cause it to become unbonded from the clutch plate.

And as usual there isn't any t.c. companies willing to share who or what torque converter clutch pistons they use. But JW has shared a little bit by showing you the differents in his and stock. Ford Super Duty 4R100 Tranny Converter Clutch Pistons Photo 10

Now I have been in search of companies that make custom torque converter parts like stators, clutch pistons for sale to the public. But I haven't had much luck. Because someday I would like to be able to have a torque converter built or rebuilt to my specs.

Now can we please hear some more torque converter talk . I am in need of input which I hope I can convert to knowledge. HeHe I am kinda like a torque converter that won't lock up!!

 

None of the converter companies will give out their specs because its proprietary info.

Giving out the specs on that special converter that Joe Converter builds will allow the next guy to copy it. So now Joe Converter has built the ultimate converter, he gives out his specs. Anybody can copy them. That means all his research was for nothing. Because everybody is making his converter. Kind of like shooting yourself in the foot.

The only way you will get info on a converter is to buy the one you're interested in then cut it open. Study all the parts then try to improve on it.

 

Interesting thread I'm keeping my eyes on this one! No meaning to hijack this thread but does somebody know about how much of a gap should be between torque converter to bell housing?

 

That is not a problem since you are asking about the t.c. Now Roland posted a photo post #39 and I do believe it should be a 1/4 inch but when I installed mine it was like a 1/8 inch. Just make sure the t.c. is in before bolting it up to the bellhousing or you run the risk of damaging your pump and t.c. Good luck

 

My 01 superduty is sitting in the driveway right now with the transmission laying on a jack. Bought the truck a month ago ford told previous owner to put a new tranny in it because it dumps oil from the TC sometimes. Truck has 116k mi on it and a ford Warrenty reman tranny in it. I bought a billet TC built to spec from PNH and waiting on racer x pump seal and transfer case gasket I ordered yesterday. I can't wait to get them and shove it all back together. I really want to see and feel how the new TC runs. I bought the truck dirt cheap from the problem and it is unmodified and clean so if this swap goes good I will be very pleased!

 

Welcome to FTE !! Sounds like you are on the right track and I hope all goes well with the install. Look forward to seeing you around.

 

Thank you... like you I desire to know more about the issue. It will make me ill if it starts leaking again. Strange thing is I have a ford 655a backhoe that just had the same problem. Pushed the pump seal out.

 

Well it isn't always the torque converters fault it can also be the pump or bushing causing it. Here is a tread that helps explain part of what can be an issue. https://www.ford-trucks.com/forums/1...p-bushing.html

 

I understand. On the backhoe the pump and TC was changed. It was just coincidental(sp) but I had two fords pouring fluid from the same cover. In my f250 bushing looks good as well as the old TC snout. Old TC is probably ok but after research if I was pulling the tranny for a pump seal I am putting in a aftermarket TC.

 

Incase anyone is wondering dealing with precision new Hampton and Racer X was a outstanding experience. I cannot vouch for their products yet but they were both knowledgable and very helpful to me.

 

I can't afford a torque converter at the moment, I hope it's OK. I was getting some Trans fluid in the radiator & over flow tank. It wasn't easy cleaning the tank. Well if I can keep her cool that's half the trans seal problem solved.

I'll take pictures as I go tomorrow. It isn't pretty I already see parts are missing...

 

If you have trans fluid in the radiator you have a leaking trans cooler in the radiator. FIX THAT IMMEDIATELY. If trans fluid can leak into the radiator, then coolant can leak into the transmission. Engine coolant will dissolve the glue that holds the friction material in the clutches to the steels. Once that glue is gone the transmission is destroyed.

 

To be honest I think many companies don't build them and you don't get the info because they don't know. I would be willing to bet most of the TCs on the market for the 4r100 are not built by who claims them.

 

Shaker!

Hope you read and understand Mark's advice to you, directly above your most recent post.

I think you are talking to me but mark was addressing mr dogbreath. If I'm wrong I'm not sure what ya mean help me
