What’s the fitting on upper passenger side of the hump. Nice work on the hump mod.

That's a magnet I used to hold the pieces in place while I tacked it all together.

My son is doing this with a TKX. He cut all the spot welds out of the tunnel crossmember and moved it back just enough to clear the trans.

So to give you the story to date up untill recently my car had a 5.0/AOD combo in it that came out of an 88 mustang that was on the loosing side of a car/truck accident. Both the engine and transmission had relatively low miles on them and the transmission also had a shift kit installed, when I purchased them from the owner who was parting the car out he gave me the paperwork to prove it.
Well I got it all in and working but it never shifted right, in any gear. Bought Lokar TV cables and the Ratio convertor for the correct TV cable adjustment, bought a set of MAC transmission guages to set the TV pressure across all ranges but it still never shifted right, one time it would upshift at very low rpms 1200-1300 the next time round it would not shift untill 4000 rpms in any gear.
So after searching and hunting for as much information as possible I came to the conclusion the previous owner beat the snot out of the transmission and I was due for a rebuild/replacement of the transmission.
While I was searching for my best options I was searching for rebuild kits, for full AOD's and I even started to entertain the idea of putting a T5 in it because it is a realitively easy swap and because I really miss banging gears.
Then low and behold I stumbled across a screaming deal on a NOS Tremec 3550 TKO with a pro 5.0 shifter sitting on top of it, that I just couldnt bring myself to pass up. (and Yes it is the tko it has the 26 spline input and the 31 spline output) It was bought originally for a 66 stang project that was sacrificed up to the horrible economy. And as I have complained.. I mean mentioned here a few times already I have been working stupid ammounts of hours. So it was a go, and I have come across a few really good deals, got a centerforce 10.4" DF clutch for $150 buy it now on ebay from a shop in california, it went so low because it had a torn box and couldnt be sold retail.

And yeah I miss having a 5 speed guess we will see how much fun it is

OK OK I will post some pics of it too.

Here is the $1000 bad boy (yes it only cost me $1000, total came to $1145 getting it shipped up here from reno) that has been taking up space in my kitchen for the last 2 weeks(seriously I have a carport and I wasnt leaving this thing outside) and yes because it has been in the kitchen all this time my 2 year old believed it was his chair/table/pony whatever you name it, so its not as clean and shiney as it was when I first got it.(and to be honest I think for the first day or two I played with it as much as he did) It does have the standard .68:1 overdrive instead of the road racing intended .82:1 overdrive.

Here is my DualFriction clutch

For those of you that dont know what a Dual Friction clutch is it has different friction material setups on opposite side of the clutch disks. This gives it a higher clamping force available with more of a streetable road manner.. Guess the easiest thing to do would be to show you

Here is the pressure plate side (note the input shaft splines)

Here is the flywheel side

So we all know that there has to be some transmission tunnel mods for this thing to fit in the tunnel because of all the different plates on top of the transmission. I have to tell you guys this honestly its allot less work then I thought it would be. Really all I had to do was trim the tunnel support bracket and everything else fits just fine there is probably about 3/8" of space everywhere else on this transmission the tunnel support was the only thing stopping it from just dropping in.

here is a good picture of the bracket im trying to hold the old peice there so you can see what I cut out

here is where it comes through the floor, (my car is an LDO car that came with a C4 and a stock floor shifter)

I will correct myself a little I did have to cut my transmission hump cover to go around the stop plate on my shifter

guess you guys wanna see it from the bottom dont you

Now some of you might recognise the high quality transmission crossmember I have holding that transmission up....(psst Frank im talking to you) The Tremec transmissions and the AOD transmissions have the same mounting points, all I had to do to get the AOD crossmember on the Tremec was clearance the back of the crossmember, personally I think it looks really good like that

Here is another good pic, this also shows my hydraulic clutch slave cylinder bracket but I dont have pics of the installed setup yet, just forgot to take a pic last time I was under the car for you guys and either too tired or too lazy right now to crawl under and give you guys a pic.

I have gotten a few things done since I took these pics, I put the driveshaft on(factory C4 driveshaft I am really thinking about spending the $300 and buying a nice ford racing aluminum one) and I am buttoning up the hydraulic clutch setup, the master cylinder is on and I just got the remote resivor mounted.
As I get closer to being done I will post more pics and hopefully next weekend I will be it again

is there a way you can send me the pics of the trans install and your hydraulic setup you did? I can't see the pics on your original post
