69mach1377 I guess we'll find out how good they put one together...hey, whatever happened to the op?

Mark Kovalsky I never bought a complete trans from Transtar, but when I had a shop I used to buy all of my transmission parts from them.

69mach1377 I guess I'm surprised the OP or anyone else is not curious about the trans source...Transtar Industries. Nationwide warranty.

Mark Kovalsky Synthetic is better, but the dino fluids are getting so good that there isn't a huge difference any longer.

69mach1377 OP, update on trans quote thru my BIL.
$1636 plus 800 core plus 186 shipping plus tax and install labor. 18m/18k warr and about a week to build plus shipping time. Supposed to have the latest updates but w/o custom options. Optional 36/100 warr for 150.
I just gave the go ahead to order and we'll probably mod the valve body for quicker shifting, maybe another 100?
I should probably fill it with synthetic from the get go, right guys?

69mach1377 OP, I just got one quote for 2495 installed for a basic unit. Upgraded clutches as desired began at 400 for 'redline'. Upgraded converters began at 200. I asked about a nationwide warranty and he was confident enough to say, "I'll give you one", only once in 10 years has he lost that gamble and had to pay. When I asked about a shift kit he said that was old tech...huh?
I'm also getting a quote from my pro mech bro-in-law, but his source is taking a while to get back to him.

Thanks again,
Yes, it is an E4OD, and no, it will not work in your Excursion. You must have a 4R100.

INFRNL I'm pretty sure the 4r100 started 99, where the e40d ended in 97. will have to wait for the more experienced but I think there might be some issues putting an e40d in place of a 4r100. It should bolt right in but lengths might be different, linkage, wiring connector, tailshaft yoke. another concern might be your pcm is programmed for a 4r100; sending those codes to a e40d might be an issue as well, idk.

4 grand for a rebuild seems a bit steep, seems that you could get one from ford for not much more. I know there are some aftermarket trannys that are slightly built for less than 4k but that also doesn't include the swap.

69mach1377 4k is about the max I hope mine will cost installed, but I would expect an upgraded torque converter for towing. I should be getting a quote soon. 4k every 10-20 years is a lot better than buying a new truck, that's for sure...

As for the Mach1, after 28 years and too much money, I got it close to what I wanted including a 475 hp 395W, Astro A5 trans, 3.5" alum DS, 9" 3.50:1 rear, R&P tilt steering, and a bad ass lowered stance. Then I broke my left ankle and could not shift worth a crap, so I sold it and now have a 2016 GT/CS that is much safer and just as fun but has many options that just can't be added to a classic w/o a huge budget.

bossbotana Yes, I plan on calling around before I pull the trigger, $4k seems like a lot for a transmission.

How's your Mach 1, I have a restored 70 Boss 302
07-18-2019 08:28 AM
69mach1377 Like I said...but a second opinion would seal that fate.
07-17-2019 06:39 PM
bossbotana Took it a shop today, they just called and said it's toast, somethings binding up in it, like throwing out an anchor when it hits 3rd gear.

Wants to do a rebuild $3500 - $4000
07-16-2019 04:21 PM
bossbotana I guess I was hoping that with enough information you folks would be able to guide me in the right direction. As much as I know about cars (older cars), I'm the first to admit I know nothing about transmissions. Guess I'll bite the bullet and take it in rather than throw parts at it that may or may not correct it.

Thanks guys, your suggestions have been helpful. I'm just a guy that like to do it my self and save a few $$ when I can.

I'll put an update when I get it to a shop.

That is correct, it is supposed to do that. It will also show first gear in reverse.

There is no 3rd gear solenoid sensor. If you mean the 3rd gear shift solenoid, there isn't one of those, either. This trans has two shift solenoids, it selects gears by turning them on and off in a pattern.

I'm not sure what causes that. I think you may need a shop manual with it's excellent diagnostic routines. Hint: If it says Haynes or Chilton on it, it isn't a shop manual. If it says either of those it is 100% worthless. You can get real manuals at http://helminc.com, or used ones are available, too.

There isn't enough information to make any determination. You could spend a bunch of money and replace both and see if that fixes it. If not, then you could try diagnostics to find out what the real problem is.

The scanner couldn't read PRND21? I find that hard to believe.
