Mine came with 3 drill bits. Directions came with recommendations were to start. I skipped their first recommendation and moved onto the second drill bit. I didn't want to do it twice and that's what others were doing at the time. ...that was my mistake...had to do it twice anyway and fab a new plate as the shift point holes were now too large. The pre-drilled were most definitely too small.

That was my particular kit though for that transmission. I suggest going by the directions.

Hopefully that helps you more. Doing it twice sucks lol.

Also my E4OD/4R100 was slipping badly, didn't want to move the vehicle. That was the purpose of the kit, but I did more work to it than just the kit.

I did this back in 06 at 185,000 miles. Have never had another problem with it since. I believe the truck/trans has 370,000 miles plus on it now.

I think that's everything...it was a while ago.







Good Luck!

 

Thanks Brew!! Good to know... I'll look at it all tomorrow. The white box on top of the Transgo kit is a brand new/updated solenoid block. There's also a new separator plate that's not in the pic. I'll measure the holes and see if they're pre-drilled, and report back.This will be my first E4OD/4R100, but Ron has done several of them. He calls that kit "Tug and Pull", but I think it just says "Tugger" on it. Do you remember what yours said?

EDIT: Yep, just says Tugger.

 

Yes the "Tugger" kit. Huh, doesn't look like it's changed a bit. It most definitely works. Saved me from purchasing another trans. $99 kit back then.

I also swapped the Aluminum pistons /plungers for steel, cleaned all the clutch material from the accumulator body...it was really thick with it.

I added a friction modifier cocktail to it to help it a little as well. Same stuff you use in the rear ends..

 

I was also following 1 sometimes 2 transmission guys advice. It was my first and last time working on a auto trans lol. Did it at https://www.tccoa.com/ way back when. The guys over there knew that trans well .

Holey crap, that was almost 18 years ago lol. 2006*

 

Ah yes, great info over there. The 4R70/4R75 "Jerry Mod" aka J-Mod was derived from an OG Ford engineer that was a member on TCCOA.

Ron told me tonight that the 4R100 is a great trans, it just has a couple of bugs. Sounds like you've found the same to be true.

 

Yeah they've been around for quite awhile. Good Guys!

 

In case you missed Rory's truck reveal... it turned out sweet! Robbie is better though... just sayin'.

 

,,,

 

Well, he did the job Rory asked for...actually better than that according to Rory. I noticed a big dent they painted over...it's now a shiny big dent lol.

I like the undercarriage work they did...should of left the paint alone now that I thought about it. Painting half **** rarely turns out well imo. It's like trying to do something you love without any heart....if that makes sense.

 

Because you can never have too many ratchet straps.
