4l80e Help

Ok let me say that installing solid motor mounts and a 80e go to gether like oil and water!! Be prepared for lots of shaking and rocking banging and prying. It took 3 of us 2 hours to line up the motor to the mounts and the 80e. Id highy recomend to any body attempting this to notch the top of the transmission tunnel at the pinch weld to gain some extra room. I aslo took the poly mount off the trans and let the trans lie on the JS man crossmember. After the motor mount bolts were in i had no problem lining up the holes for the poly trans mount and JS man braket fit perfect! Now the bad!! I noticed when installing the Gilbert prop shaft that the shaft hits the shifter leaver braket badly!! see pics!!
I also noticed that when i went to install the propshaft bols into the rear of the transfer case that i couldnt turn the shaft. I thought mabey it eas in park or in gear. I shifted threw all the gears and still cant turn it. I also shoved the rear driveshaft yoke in and i coudnt turn that either!! What the hell wrong!!! George Help!!



I aslo noticed the c clip that holds the shifter cable is loose as hell is that normal look!!

Re: 4l80e Help

That's normal. The 80e has a lot more resistance just sitting than a 700 does. Pressures actually release things to allow movement. Some of the resistance is the bushings too. A junkard or used 80e turns easier because the bushings are worn out. The ones I do are very tight to keep lube where it's supposed to be. Your fine. You haven't hurt anything. Now Gary ran into a similar problem and the lever wasn't adjusted correctly and it was still in park. The pan should only have a little fluid in the bottom from dyno so your good there if you want to drop it down to fine tune the shifter adjustment.
The C clip you have in there is in the wrong place. You are supposed to use the stock one in the area you are looking at in the pic. Scroll down through my forum and you'll see how to install it. The "tight" issue may be due to incorrect adjustment:
http://www.syty.net/forums/showthread.php?t=42618
These pics delineate how that cable goes in. The two E clips I gave you go inside along with the stock E clip to align everything there. Then the stock "U" clip goes back in place in the JSMan bracket.
The gilbert prop with the manual shift lever interference is normal. Scott at Detroit Turbo sells a custom stainless shift lever that is narrowed or you can just bend the stocker over a little. Most just bend the stocker. Don't worry. That's standard gilbert clearance stuff. That shaft is huge and has clearance issues with the 700 also. No one has EVER broken one of those. Well worth the adjustment headache.
That's really good to know on the solid motor mounts! I'm glad you have a camera too. That really helps other guys when they look up these old threads. Please leave those pics up.

Re: 4l80e Help

yes I the top will hit or come close to the larger bellhousing. I did not know that till it was to late. Mine is in but is right next to the sheetmetal. I hope it does not mess anything up.
You need to bend the bracket or buy the gilbert bracket from Detroit turbo.
Mine did not spin either. Look at the georges "ask" section. Its real tight. For some reason Mine got easier after a few hard rotations. I put the truck on jacks. Blocked one rear tire and spun the other one till it spun. Make sure its in neutral. 2rd slot back from all the way foward.
Check the clip. It could have been bent when you removed it. Mine is tight.

Re: 4l80e Help

Tight is one thing cant turn is another! I even removed the cable all toghther so adjusted or not shouldnt matter. Hey george i tried turning the prop with a pipe wrench wraped around it too, it dont budge! same on the rear of tranfer case ( drive shaft side) Wont turn all. U sure this is normal!! I spun the transfer case around a few times before i bolted it up to the transmission it seemed fine then. ???????????

Re: 4l80e Help

Mine did not turn to. I pushed the truck as hard as I could and it would not move. To give you an idea who hard that was, I lifted the and installed the 80e by myself.LOL
I worked through the gears a few times and it came lose. Not sure why. Maybe it was not comming all the way out of park. I was worried too because my TC spun free too.

As i said above the shifter cable isnt hooked up at all so a poor adjustment can t be it!!
ill finish up everthing else i have to due and deal with it when the truck runs again hopfully by this weekend im getting closer everyday.

Did you use the trans cooler in the rad. or bypass it and run a b&m cooler.
I was going to bypass the rad and run a b&m upfront with stainless lines.

Re: 4l80e Help

mine was not hooked up either. It was at first. but even with it removed it still would not spin.
I have the rpm lines hooked to the 700r so i just flushed them out and used the radiator and b&m cooler. George said i could bypass the radiator and be fine. Trans is a tight fit. I should have mine running in a few weeks too. Just waiting on my DP to get coated. truck has been down for 7 months :(

:rotf: thats sound too much like me :rotf:
I say we start them up at the same time.
If you click my mods you can see all I did in that time.
BTW where did you put the trans controler?

It turned fine when it was done. Didn't act funny on the dyno. If you have issues send it back but this is why I dyno them. When they go out, nothing is wrong with them. Did those pics of the cable install help?
Also, Jeremy had to beat the top lip of the trans tunnel on his because of the engine mounts. Solid engine mounts set everything up a tad bit higher.

Re: 4l80e Help

Hey, Frank, the selector arm you want is this one:
gilbert%20lever.JPG

You can get it here:
http://www.detroitturbo.com/cart/product_info.php?products_id=290
I though of something on the trans. The parking pawl is probably engaged even though you've moved the manual valve. If you used a pipewrench, it's probably hung up now. Drop the pan and follow the rod back toward the corner of the case on the driver's side and see if the parking pawl is still engaged in the rear planetary. It will NOT move if this is engaged.

George will it disengage once i power up the trans and start the engine. Im only about a day or too away from that!! Or due i need to pull the pan first. Oh yes the pic was very helpfull of the shifter cable connection.

Re: 4l80e Help

Hey Frank.
I'm gonna send some pics in a little bit.
I want you to take the rear servo lineup out. It's REALLY easy. I want to check to make sure the band is OK. I'm worried that it may have twisted up if it was in park and turn with the pipe wrench. Once the servo is out, try to turn it again. If it turns freely. Then we can fix it from there. It won't take a removal. We can fix it in the truck. Give me just a little bit to scan the pics and put them up.

Re: 4l80e Help

Here's the puppy:
4l80e_servos.sized.jpg


There will be six 10mm bolts. Take those out and drop the low/reverse/park servo cover off. Let it down slowly. There may be some fluid in there from dyno and there will be some assembly lube also. That stuff doesn't break down till it's up to full temp. Once you get that out, look up inside the hole with a flash light.
It should look like this:
abb.jpg

Let me know what you see.

To everyone, I'm really sorry. I've got a forum for this stuff but we're kinda out here since the question came in out here. The pics are big so Frank can see the stuff better and I apologize for load times for everyone else trying to look at it.
In the future, please do NOT take a pipe wrench to ANY rotating assembly. Driveshaft, output shaft, anything. I put these in park when I send them out and if you tried to twist that thing in park it may have wrapped this band or damaged the parking pawl. We'll check them both though.

Hey george when i tried to turn the front prop shaft i didnt force it very hard im sure the truck on the ground on a slope would of put more pressure on the front and rear driveshfts!!
Im not a total idiot!! I would not of forced it that hard, I just couldnt turn it with my hands to install prop bolts so i used the pipe wrench for some leverage. Ill pull the pan now and take a peek.

Re: 4l80e Help

Ok i removed the round cover and a bunch of little pieces of metal fell out and it smell burnt!!!
Only kidding it looks just like the pic theres a little flat shovel looking thing in there that the rod pushes up on! It was a bitch to get out with the valve body not removed i hope it slips back in easy. I took a pic ill load it in a few!

OK. Number 1, your a dick!

Number 2, that looks perfect everything is still where it is supposed to be.
Now try to turn everything. If it's still just like it was before AND the parking pawl on the trans is released, then it's not the trans.
If it turns easier, let me know and we'll fix the pin. It only takes a bend of a few thousanths the wrong way and it'll cause problems. Not a big deal at all.
