Hey "luv-my-2002-p71", Is the Dynotech driveshaft an equivalent to the AMMX? I bought mine because it was cheaper than the dealers part and also balanced at 6,000 RPM's. As I said before; "you stole that driveshaft!" Are you still pleased with the trans? Did any issues come up? Did you alter any tune or shift points with it? The most important question of all....What is your first name? "luv-my-2002-p71" is hard to type for a bad typist as myself. 
hehe, I should put my name (Eric) in my sig. Yes the driveshaft you got I'd say is just as good. The AMMX shaft is unique in that it weights 17 pounds -- with steel linkage and both U's. This is the same weight as a standard P71 aluminum shaft except that it is 30% stronger than aluminum.
Re Shifts: Yes, first gear was shifting early as the accumulator is a bit larger, so you'll have to raise this up a bit. I'd recommend getting a tune from Lonnie at BOC afterwards -- he works with darren and knows exactly how to best set it up with a tune.
BC Automotive could be charging a lot more for the quality that they sell, especially seeing what the other garbage transmissions out there going for dollar wise.
-Eric

I was having long delayed shifts, hunting for which gear to be in and noticeable slipping as I was accelerating. The car always seemed to have the slipping while hard accelerating issue since I bought it with 12k miles. Since it worked fine otherwise, I just overlooked the problem. I maintained it with fluid changes at 30k miles.
If I kept the original engine in place, this might not have become a major issue so soon. The DOHC seemed to cause the slipping while accelerating to become much worse.
While meeting up with MM.net member MM-BKK to record his exhaust video, I noticed how well his car drove and specifically how well it shifted. Around the same time, I came across other peoples trans swap threads. This caused me to consider that my current drivability problems could very well be with my trans, and not the engine or the tune from Dennis.
I had my choices of vendors narrowed down to four, Darrin being one of them. Glad to have chosen him as he explained a few of the differences of his build vs. others. I would not have been happy with the other vendor's builds.
After a few phone calls & PM’s, Darrin provided me with the best 4r70w that he builds.
I was concerned that I might not really need to do this repair, but the car definately needed it. The trans fluid was a reddish brown color when it was drained. This is only after about 4k miles on new fluid!
It is installed now & I only drove it about 20 miles so far in mixed city/highway driving.
Well, it shifts pretty quickly, more like a switches gears with almost no perceivable delay. The shifts are in an instant and I love it!
Nowhere near as hard shifting as I thought that it would be. Very sedate shifting as a matter of fact. Now, this is with mild acceleration as I was driving in commuter traffic on a mixed city & highway road in the rain. Even the downshift was milder than what I was expecting. It is definitely there, but in my view, very mild at 30 to 20 mph when it occurs.
Darrin settled my concerns by explaining about the milder shifts won't hurt a thing. It’s just not banging the finish pressure on the shift. The fact that the shift is instant is what is important. If you want to firm it up then go at that with line pressure in the tune.
Darrin did some things that might make this transmission shift fairly mild at part throttle and on the coast downs because he noticed that I seemed to have concerns over this. So this is good news that it is behaving like he built it to.
I would like to comment that Darrin indeed does listen when you speak with him!
Don’t know if this is because I wanted to feel this way, but the butt meter says that the car accelerates faster now. I’m thinking that the trans was slipping quite a bit more than what I had previously perceived.
There seems to be "slipping" as it engages the OD, the dreaded "flare" that we read about occasionally. It sounds like the engine revs just a little higher for a very short time before engaging while shifting into the OD. Darrin explained that this is just how it is with these trans. He could have reduced the flare a little at the risk of breaking things, just not worth it. He assured me that this is normal and shouldn’t damage anything.
I won't change a thing since this set up won't hurt anything. This should keep that passenger seat quiet (my wife).
She already dislikes how “noisy” the car is now since being altered with the DOHC engine.
I still need to go full throttle, without my wife of course, and let you know how it feels then. I’m waiting on a few parts that I want to install before I go back on the road with it.
Darrin, please feel free to comment on any corrections if you see any need for it.

Thanks goes to Eric "luv-my-2002-p71", for starting this thread which was one of the threads that I eluded to.
Eric, now that you have this trans a while, are you still happy with the results?

Darrin does excellent work. We spent til LONG into the night (morning, actually) chasing down some issues while we were working on a tune - calling across country for backup from other modular specialists(LOL) . . . old-school pride in workmanship and a non-slacker work ethic.
He's knowledgable, hospitable, and a straight-talkin' guy. I've been dealing with parts guys, machine shops, trans guys, and other people modifying street cars and building track cars for 25+ years. It's a rarity in the performance business, frankly.

In all fairness, the "information" of my review came from Darrin himself, I re-wrote our PM exchanges, creating a summary that you just read. I'm not that smart about Trans. That is why I mentioned for Darrin to offer any corrections.

I wanted to add, IMHO these trans are pretty tough even in stock form. I drove it aggressively with the problem from 12k to 100k miles. With the stock engine, the slipping only seemed to show up under very hard throttle, that is why I ignored it. When I got the DOHC swap, TQ converter & LSD 4.10's done; the slipping started to get much worse in only 4k miles.

Oh yeah, it's great. Still love it. Had the music turned up this AM and I was jamming which always seems to shorten my commute time I have roughly 350hp at the crank now car just plain moves! No way would it move like it does without Darrins transmission.
I am going to change the fluid every spring!
Tom: what did you get for a converter?
Lastly: when are we gonna see a 1/4 mile time??

Glad to hear that you still like it! I ask because sometimes people can easily convince themselves that something is great initially. Then as time marches on, a better evaluation can be made.
I have the PI 3000, triple disk--I know it's not the favorite in the panther world, but I can't dish out that much dough on something that I already have that works.
1/4 mile? Still have the exhaust to finish, should be in the next three weeks. Does any tracks in PA run in the winter? Otherwise, it will have to wait until spring.

OK, another update...
I found out that Ford requires the replacement of transmission cooler when a trans fails. Tran’s failure is not only where operation is inhibited, but also described as anytime particles of clutch material or particles of metal are found, or discolored fluid indicating scorched clutch materials. The reason is that the 170 deg. Flow Control Valve prevents proper flushing of the cooler.
See these pics, numbered 31 through 35, for details.
http://pasig.myphotoalbum.com/view_photo.php?set_albumName=album08&id=FULL_VIEW_BACKSIDE_LABELLED
The current cooler part number is YW1H-3F479-AC, previously YW1H-3F479-AA & YW1H-3F479-AB. The replacement appears to be very easy. I will swap it tomorrow morning.
Contact Ray, "TheDealer" for a fair price on this item.
Also learned from Darrin...Do not ever put anything into a Torque Converter other than Mercon V in efforts to clean it! For example, Safety-clean or Brake Cleaner, these will dissolve the glue backing from the Lock Up Clutch material. In addition, these fluids are NOT compatible with Mercon V. When you run the transmission, the fluid and particles will foul up your new trans. Fortunately, my mechanics did not do this. The proper way to clean a TC is to have it machine flushed at a dealer or send it to mfg. to be cut open for service.
The main lessons that I learned from this is to always replace the cooler at the same time as the rebuilt trans is put into service. Also, replace the torque Converter or have it properly flushed if you intend to re-use it. Otherwise, you may risk potential contamination of the clean trans. This is where the application of the Magnafine filter is being used to try to alleviate said contamination.
I hope that this info will help others when they face a trans repair. Darrin has been extremely patient and helpful with his knowledge & experience. I highly recommend that you contact him with your specific trans needs.

Will do part throttle & WOT update in near future.
