4l80e Intermediate Clutch Situation

Need some help on my 4L80E rebuild. I have gotten pretty much everything buttoned up from the center support back. I went to install my intermediate clutches into the case and proceed to close up that assembly with the TransGo snap ring. After installing the snap ring I couldnt even turn the clutches with my fingertip, nor could I get a feeler gauge in behind the snapring to check a clearance! Thinking I did something wrong, I took the clutches out and put them back in and put the snap ring on. Same thing. My center support bolt as well as the cooler line were lined up on the money so I knew it had to be in my friction/plate assemblies. I mic'd my new steels and my new Raybestos Stage-1 waffled clutches (pictures attached) and found the difference was in the clutch plates (not the steels) stock looks like about .070 and my stage ones look about .090. I bought all the clutches in a kit and the rest went in like a dream. Why would they give me some crazy ass intermediates? I need these clutches as fast as possible and being a holiday weekend wittrans.com wont be back up until monday morning (the only place Ive found that gives me dimensions on the clutches). Anyone got any advice or even a solution on why I have one crazy set? Thanks!

Schmids5.3, yes I am putting a transgo reprogramming kit in it (the HD2 kit). It comes with a heavier duty snap ring, however it is not the culprit in this situation. They give you that because the stock one can release in a high RPM situation. I dont intend on anything high rpm, but Im putting it in for good measure.

 

Svensk, No sir, it is not a Z-Pak...At least I didnt get any information at all saying it was? They all came in a kit together (forward, direct, intermediate, 4th and overrun). Here is a picture of the friction kit I got before I opened it. The intermediates are at the very top, with the skinny overruns stacked ontop of them. Besides they dont make a Z-pak for the 4L80e.

 

...No wait...Isn't the Zpak one MORE? not one less, although one less would help the whole pack assembly shed heat better. Besides, Zpak is for 3rd gear holding power. 3rd gear is on the shoulders of the directs, which is the next assembly up from intermediates going towards the front pump.

EDIT: After reading the sales flyer or whatever you want to call it, off of the raybestos site, it looks to me like 91-95 had a different set of intermediates, compared to 95 up. Scroll down to page 4 if youd like to see what Im talking about:

      2001 GMC Sierra - Banging feeling in steering wheel

      By txab · Posted

      Without knowing how bad your banging is, one suggestion is the intermediate steering shaft on the steering wheel. These used to be a problem on 800 and earlier series. The feeling/sound was sometimes described as "clunking" and was felt in the wheel. Also there is a plastic piece in the lower column that is referred to as a bearing. Not your traditional looking bearing though. Your ball joints, bushings and tie rods or steering rack (if equipped) are the main point of issues. You never mention total unit miles, only that you've put 60k on it.   You can search the site for help on the ISS description. Plenty of these have been replaced   https://duckduckgo.com/?t=ffab&q=site%3Agm-trucks.com+intermediate+steering+shaft&ia=web

      Yes I have is set with the 1mm disk (Minumim Tension), for spring spacing and I raised my truck in the rear 1.5". You can go 2mm  and I think 3mm if you need.Minimum. We are on our way to TN from GA.. My wife is driving and stated she cannot believe  and   stated she can not belive the difference.

      Most 1 ton trucks come with the factory overload spring, which need to be removed for installation of RoadActive Suspension. Removing the overload allows proper fitment and ensures the system works as intended. The RAS® Mega-Duty kit will reduce squat and provide significant improvement vs the factory overload spring.

      I wonder as well, why they would send me a text message with links to these suggested procedures totalling over $10,000 without even the slightest hint of how they arrived at these being necessary.

      https://precisionlubrication.com/articles/oil-filter-efficiency/     For them it is a problem of $$$$ and compliance. To cover both they have to lie from the heart.    Government wants low waste oil numbers so the bar needs to be very low on contamination to met that requirement.  Consumer wants cheap maintenance (perceived cost). Again requiring a low bar.  OEM wants high margins at a cost effective warranty rate and lots of repeat customers. More low bar.  Filter manufacture wants the same thing the OEM wants. See the pattern?   Consumers are fickle and also want perfection requiring a HIGH bar. Inconsistent with all of the above. Consumers can be, when the put their minds to it, inquisitive, love winning arguments which requires some useful information to be available to support them. And this is where it gets sticky and the lies begin.    Information needs a solid well grounded point of reference if we are to compare in a useful way. There is a standard for this.  ISO 4548-12. This standard sets the particle size at a specific Beta ratio and darn few are faithful to its intent.    If they don't state the test method they change the particle size or the Beta ratio to hit a perceived favorable standard. They obscure the information in a way as to prevent direct comparisons leaving the consumer with one method. UOA's with an ISO 4406 test result. Pricey and not allot of labs willing to do the work. Lobby work happens everywhere, not just at the seat of government.
