Info on 4r100. Transmission
I've tried searching out info on the web but I can't understand why this bypass tube banjo bolt has a ball and spring in it is it to hold fluid for the torque converter. The other check ball and spring is in the tube it's there just in case the cooler gets plugged or messed up in any way but the other ball and spring in the bolt confuses me. Why bottle neck fluid if you don't have to. Any ideas on this and would it be ok just to take the ball and spring out of it. It might take a few seconds to fill up torque converter but if it'll make tyranny cooler by letting fluid trough faster I don't see the problem of removing it. Any ideas on this subject would be great

Hey guys I could really use some advice on this. Please

I had a V-10 Excursion with that tranny,...thankfully never had any troubles with it. I know that isn't helpful at all. The right person just hasn't seen your thread yet.

Yes I agree they are good transmission but I got 238k on this truck and I don't know how the previous owner took care of it so I just wanted to learn from some of the guys who have worked on the 4r100 and see what they think

I hate to send you elsewhere, but you should be able to get an answer from other forums where Mark Kovalsky is a member. He is a retired Ford transmission engineer and knows the 4R100 inside out.

I spoke with Mark and I must say he is very nolageable. But I'm getting two different stories. Both men and transmission gurus. One said removing banjo bolt ball and spring just takes out a huge bottle neck and the other one said not to do it cause I'll lose a lot of fluid on the ground and probably get a lot different pressure reading. So I don't know who's right or wrong but I've got a new banjo bolt with the new bypass tube I bought so I'm gonna take old one remove spring and ball and just try it. If it don't work then I have the new banjo bolt to put back in. Hopefully won't loose to much fluid. What do you guys think???

I would think that if you're just removing the spring and ball and putting the banjo bolt back in, you shouldn't lose any fluid. I may not be seeing the whole picture though.
