Re: 4l80E install. Transfer case does not fit.
Those fit differently because there are different manufacturers of those seals that you guys put in there. Some are actual O rings. Some are square cut but very thick. Some are square cut but very thin. Basically a paper thin coating of permatex is all that is required. Gary, you were very patient. You picked THE hardest upgrade for someone to do. This is FAR beyond an intake manifold swap or a turbo bolt on. Once you do it though, you'll never forget. You'll see what I mean. If you ever see someone ask a question about the 4L80e in the future, you'll know first hand and it will always seem like you just did it.
First thing you'll notice is that the big delay bang 1-2 shift will be gone because the ratio change won't be so dramatic. Resulting in a much smoother shift.
I got to watch Jeremy and Will race today at Hamilton and I love the 1-2 shift. You see just a little wiggle and that's it. Very smooth but quick. I recommend you give the "Performance kick" a try also. Don't go ANY higher than 25% though. You may feel like 25% is too much. Don't leave it there. When your done racing, flip it back down to normal.
Spare rubber glove with duct tape or a zip tie works really well
Would you have the part number handy for that 45? I may start including these in the kits for guys wanting to go to AN fittings with braided lines.
Frank, you did cut some length off the bolts and torqued them, like Gary did, right? 35 foot pounds is the normal torque. The pic you took with it on the floor looks OK but the pic you took with it up in the truck looks different. Is the case wobbling around or is that an illusion? If it's torqued and you trimmed the bolts like I told you to, don't worry about it. If you didn't trim the bolts then you'll have to take it back out.

Re: 4l80E install. Transfer case does not fit.
Here's the pic I'm talking about:
It may just be the angle or just a REALLY thick gasket in there. As long as you torqued it and it isn't moving, your good. I don't know if you noticed, Frank, but I had to drill and retap one hole. It's the only bolt on the pan without a flange on it. It's slightly bigger. No biggie, just don't try to put it in another pan bolt hole.

Re: 4l80E install. Transfer case does not fit.
Those bolts are for the propshaft. I need to put some pics with the instructions.
They go on the transfer case end. These eliminate the star bolt setup that likes to strip so easily.
That looks MUCH better!!! That's the way it was meant to fit. Did you guys use the new transfer case gasket?

Re: 4l80E install. Transfer case does not fit.
yea the first time i used it. It was destroyed when i took it apart the second time so i just permatexed it this time. I thought thats what the bolts were for. FYI you should include a longer bolt for the transfer case brace to transmission bracket The stock bolt is way to short with the spacer in!George Blake said:

Re: 4l80E install. Transfer case does not fit.
I had to go to OSH and get a 5 or 51/2 in bolt for mine. I cant remember exact size right now. Looks better now. Ahhh...Your spacer is longer then mine. Thats why I had to use washers to make up the difference.autoaddictions said:yea the first time i used it. It was destroyed when i took it apart the second time so i just permatexed it this time.

Re: 4l80E install. Transfer case does not fit.
Yeah, the spacers in the kit don't normally have the probelm yours did. I don't think I sold you yours though. There's a couple things guys want. I'll do that bolt. 5 1/2" bolt? Others are wanting a different shift linkage arm for the gilbert setup. I should start including those too. If there is anyting else you can think of that would've made it easier, please tell me. There's always room for improvement on any product.

Re: 4l80E install. Transfer case does not fit.
my spacer looked shorter then in that pic. I had to add 1/4" of washers to it. My kit came from JS but I bought it off a member who had it and did not use it.Could have been an old kit that was now is changed? I ended up buying 3 bolts. 5, 5 1/2 and a 6 inch. Not sure whitch one I used.
A 45* fitting would be nice too. The gilbert shifter would be cool too. I just bent mine for now but will hit up DT for one. Your TCI setup worked great. dont think you need to change anything there. Maybe inclde the schematic on this site.

Re: 4l80E install. Transfer case does not fit.
Dexron III or Type F. Type F requires a tad more maintenance as far as fluid changeouts and temp monitoring but if you want a little firmer shift, it's the way to go. DexIII requires much less maintenance as it holds up to higher temps better than type F. Use a brand name. I listed them in Jeremy's link (Thanks Jeremy!)

You posted in the thread:lol:
That's for my customers only anyway. Yeah I know others will copy it and use it for themselves on their ebay controllers but they end up coming back to me anyway.
