Not saying I am right, but I swear, the rubber gasket/pan groupset uses longer bolts. If you are converting the pan to use the rubber gasket, using the shorter stock bolts on the rubber gasket/pan groupset will have less threads in the case and therefore no bottoming out. Probably stripping out the treads.
Either way it's safe to say, use the right bolts for the application.

is that what you mean? The elastomeric is a rigid plastic carrier with 2 sets of o rings running the perimeter and need a flat surface on both sides
Cheap filter kits come with a rubber gasket, but the original cork looks like rubber after 20 years and feels like it
but the pan has a raised edge to pinch the cork gasket firmly, and the cork compresses more. so you may be right i possibly have it switched around, so either way you risk not engaging or over engaging with the wrong bolts
heres the original style bolts (like the new poster trying to pawn off)
the bolts are here to just not lose them in my gravel
heres the cork

Bigger=larger diameter
Longer=the length is longer
The bolts are the same diameter, not bigger. You cannot install a bigger bolt because although the gasket is rubber, it's actually rubber coated metal.
I'm not confused which bolts are required. The bolts are not bigger, but longer. Pictures are not needed.

There are plenty of smarter people than me, but I believe all 4R100 use the rubber gasket. So yes, the pan, gasket, and bolts are a different part number. I also believe that the later year E4OD switched over to the rubber gasket. My 95 was the old pan, so I believe it was 96 that those items were changed.

I feel like youre not reading what im saying or replying to the things I have said.
Its not rubber, its elastomeric. big distinction since cheap rubber gaskets are sold with filters and are junk.
Also, the change is a 96.5 model year change. my 1996 has the previous / early design , just like your 95 would have, and the girl who revived this chat.
The change in 96.5 required new bolts and a new pan. the entire perimeter of the pan is different because of the design of the gasket, and the overall change in thickness of the pan and the new gasket necessitated a change in length of the bolts

I am reading and understanding what you have posted.
The pan is different because there is a shoulder on the older pan that surrounds the bolt hole. This shoulder is used to prevent you from compressing the cork gasket. This shoulder is larger diameter than the hole of the rubber gasket. You cannot lay down this new gasket flat against the old pan.
The factory rubber gasket is rigid because there is a metal sandwiched between this rubber [a lot like the Factory valve cover gaskets on the last few years of the 351/5.8]. I'm certain there are aftermarket gaskets that are rubber and can be folded up and straightened out again. The factory metal versions cannot be over compressed because of the metal inside the gasket.
As for the entire profile being different, I'm lost on your definition of 'profile'. The transmission cases are similar. The mounting holes are the same spacing. The differences are the pans and the metal shoulder around the pan bolts. Sure, there may be some other differences but both pans would mount on both transmissions.
I hope we can both agree, whatever you want to do use the right combination of bolts, pan, and gasket what ever way you want too go.
I commented on this thread originally because the term bigger was used. Longer was more appropriate. A bigger bolt would not fit the transmission unless you drilled and tapped the bolt holes with the appropriate thread pitch.

I havent seen an OEM gasket, is the elastomeric one like this
or was it like this?
cork style pan
THIS IS WHAT I MEANT BY PROFILE, the formed areas that were designed to pinch the gasket. the gasket and ridges combined with their bolts took up a different amount of space than the later gasket/pan

4r100 pan, but the flat is like the late elastomeric e4od pan

The picture was only used because it was the first one I found with the flat flange.
I dont know why you are so upset over this, or ignoring what Im typing and responding to things im not saying

Upset? Not really. We have different opinions, why would I get upset? Even if we disagree, why would I be upset. I am a professional auto mechanic. Ask any of them, we are perfect and never wrong 
. Yes, that is a joke.
This thread should have never been reopened. Matter of fact, it is foolish to keep this thread going. My only comment was that bigger is the wrong term if the bolt is just longer. That is it. Bigger bolts are larger in diameter and the bolt diameter is the same for both transmissions.
All those pictures you posted does not show a factory 4R100 pan gasket. Everything you have posted proves your opinion, but has nothing to do with a factory 4R100 pan gasket. I tend not to comment on aftermarket stuff because I tend to use OEM when it comes to important stuff like sealing. I like less comebacks and so do my clients. I never really read your comments since it had nothing to do with a factory gasket.
If indeed the 4R100 pan only comes deep, you have a point that use the right filter for the application.

heres a screenshot from what Ive sent. Its easy to miss things you dont read. I was looking for your expertise/experience.
I process throughts and language differently than most, but the things I posted were either to demonstrate what I was talking about, establish clarity, or to post examples of things which I was hoping to know which (If either) were the original gasket,
here i was trying to find out what the original was like, because if it was the black one above or some other design, I would owe you an apology because a majority of the argument earlier would have been me using the illustration in the TSB, whereas i know you were a mechanic and dealt with these things at the time and many of them, and would like to draw upon that knowledge.
Sorry.

It's not an argument. Just two people sharing opinions. It's too often people share opinions and get upset. I am not one of those people.
I'm here to share that bigger is not the same as longer. This gasket thing is something that has been hashed out long ago. Just like this thread was originally opened.

A/T - E4OD New Design Elastromeric Gaskets
Article No.
96-3-22
01/29/96
TRANSMISSION - E4OD - NEW DESIGN ELASTOMERIC GASKETS FOR MAIN CONTROL COVER AND BOTTOM PAN
LIGHT TRUCK:
1996 BRONCO, ECONOLINE, F SUPER DUTY, F-150-350 SERIES
ISSUE:
Some E4OD transmissions built after December 1, 1995 will contain an elastomeric-type gasket for the bottom pan. This unique gasket replaces the previous cork-style gasket used for production. The elastomeric gasket has improved durability and sealing capability and is reusable.
ACTION:
It it is necessary to remove the bottom pan on an E4OD transmission containing an elastomeric gasket, clean, inspect and reuse the elastomeric gasket if not damaged. Torque the pan bolts to 14-16 N.m (10-12 lb-ft).
NOTE:
CORK-STYLE AND ELASTROMERIC GASKETS ARE NOT INTERCHANGEABLE. DO NOT INSTALL AN ELASTOMERIC GASKET ON A TRANSMISSION THAT ORIGINALLY HAD A CORK-STYLE GASKET. DO NOT INSTALL A CORK-STYLE GASKET ON A TRANSMISSION THAT CONTAINED AN ELASTOMERIC GASKET.
NOTE:
A UNIQUE TRANSMISSION PAN AND RETAINING BOLTS ARE REQUIRED TO USE THE NEW ELASTOMERIC GASKET FOR PAST MODEL SERVICE. IF THE TRANSMISSION PAN IS DAMAGED AND REQUIRES REPLACEMENT, A KIT WILL BE AVAILABLE. THIS KIT WILL CONTAIN A TRANSMISSION PAN, ELASTOMERIC GASKET AND TWENTY (20) PAN BOLTS HAVING AN INCREASED LENGTH TO ACCOMMODATE CURRENT AND PAST MODEL USAGE. CORK-STYLE GASKETS WILL BE RETAINED FOR SERVICE WHEN A NEW PAN IS NOT REQUIRED.
