Ok guys, the phoenix is forming within the ashes. I will begin a teardown, inspection, and rebuild of my 47RH automatic transmission on the Lung. Along the way I'll shoot some pics and post some ramblings about what I'm doing. Transmission will be upgraded with the following:- Billet SFI rated flywheel- Billet Input shaft- Billet Intermediate shaft- increased friction/steel counts- upgraded hard parts: servos/accumulator piston/billet strut/anchor/4.2 apply lever- Forward pattern manual VB (haters gonna hate)- aftermarket stacked plate Derale heat exchanger with fan, mounted in the bed- deep sump derale pan with cooling tubes- gated shifter, mounted on fabricated console. either ATI or Winters/Art-Carr style.- since OD and TC lock are electrically controlled, I will be incorporating some type of easily manipulated switches on/near the shifter to switch them on/off.- will be removing factory fluid coolers as well.The idea here is capability of withstanding abusive shifting and ~600whp (currently at 520). I currently have a triple disc TC that I will be using, it's a Goerend '15-blade left cut stator' model. The stall is lower than I would like it, so after the rebuild I may send it off to be tweaked. I'll also be doing a bed mounted battery setup to go along with the mods. Note that I am not a transmission pro, and this is my first trans build. I will be armed with a 1995 dodge FSM, an ATSG trans manual, and the minds and mouths of http://www.competitiondiesel.com. This is a WTFab production.

I'd be interested in seeing how you have all this plumbing arranged
4/1/2011 5:06:15 PM
whp is one thing but 600whp on a diesel is earth shattering torque.....

^yeah mon!^^urite, should be like 1000ft-lb currently (lost tach sensor on dyno run)^^^outlet port of trans, flex hose to cooler in bed, flex hose from cooler to inlet port of transmission - simple enough no? COoler will be mounted appropriately, and I'll do a thermostatic fan controller
4/1/2011 9:30:28 PM
AnotherProduction.And honestly, why bother with thermostatic control? Just run it with ignition?[Edited on April 1, 2011 at 11:42 PM. Reason : world's largest picture]

The notch is actually intended for a future mounting location to hold the transmission vertical; also provides the elusive 'inside corner' for hammering the fuck out of something.
4/4/2011 7:18:54 PM
http://www.youtube.com/watch?v=an87VwrH3sYchew on this for a while. you can hear the trans slipping during the run; I've got some tuning to do as well... gotta get that transient fuel delivery spot on
4/5/2011 11:18:47 PM
honestly i know jack about diesel tuning... how do you go about fixing transient fueling ?
4/6/2011 2:31:31 PM
^ here's the short answer for my particular injection pump (Bosch P7100)function:When you go WOT, the gov lever, item #3, moves forward, and hits #1 (#2 limits total fuel delivery). As boost builds, #1 slides forward on it's shaft, allowing #3 to continue to move forward until 'full fueling' is achieved.Assembly #6a is the Aneroid Fuel Control Housing - boost referenced fueling control. It controls the available fuel delivery via spring tension/rate, and boost signal from the turbo. As well the governor spring setup (shown below cap #4) affects the initial engine accelerating response and overall fueling rpm range of the engine; it works in conjunction with the AFC to provide the overall transient engine response to fueling/tuning.EDIT: the overall goal with optimizing transient fueling is minimize the amount of smoking before boost builds, decrease 'boost lag', and maximize powa![Edited on April 6, 2011 at 3:01 PM. Reason : -]
4/6/2011 2:53:23 PM
I was gonna ask you why you didn't do just like the rest of us morons and loosen the AFC spring to the point that she goes to full fuel immediately upon positive manifold pressure...but then I realize your P7100 with a heavy fuel plate will fuel much more heavily than my VE.I guess in such a case, not only are smoke limits totally thrown out the window, but that much excess fuel can quench your fire, lowering exhaust temps and lagging a big turbo...
4/6/2011 3:24:22 PM
^^ effing awesome... thanks....
4/6/2011 3:46:40 PM
^^yep. I'm currently at 20deg timing as well, so power delivery is shifting toward mid-range. Im going to have to play with getting some fuel to 'get it started', then dial in the spring rate/seat height/etc to keep it lean once it gets going. Lots to do!!!^ [Edited on April 6, 2011 at 3:54 PM. Reason : -]
4/6/2011 3:53:38 PM
Pretty aggressive timing, yes? What speed do you have your engine governed to?
4/6/2011 4:39:21 PM
well, im ashamed to say its ~3,700, with a 4k kit. It probably needs some tuning as well, as I tried a few setups before my dyno run last year and run out of time where i was. It idles @ 900rpms, so i need to do some play with shims & shit. I tried a modification that a guy suggested, but it didnt work out as intended - the '3200rpm' mod, where you remove the smallest pair of springs from a 4k kit. Supposed to fuel harder to 3200rpm than the 4k's, and be more usable on a street truck.Part of the trans build is also to install my 60# valvesprings, and purchase HD valvespring keepers & locks.And yes the timing is on the low end of being aggressive, but the guy who built my injectors recommended the setting based on the injector build/pump/power levels/etc.[Edited on April 6, 2011 at 4:52 PM.

I have a really n00by question. Why is an automatic okay on a performance diesel? Seems like in most any sports car application, a manual is the only legitimate option, but I've read about several performance diesels (and I've read about very few in total) that have automatic transmissions. Is it just because a clutch would need to be ridiculously heavy to handle all the torque, and thus, a PITA to manipulate? I'm just guessing here.
4/6/2011 4:53:28 PM
4/6/2011 4:56:44 PM
Thanks, I was just curious. I am intrigued by, but don't know shit about diesels.
4/6/2011 5:02:30 PM
Thanks for the explanation on the injection pump. I think I'd rather mess around with that than a carburetor. I frickin hate carbs.You guys should've seen the 6.4 PowerStroke I saw at the dyno a couple weeks ago. over 800whp and of course no reading on the torque. I think if I ever got into diesels it would have to be a newer electronically controlled common rail design

not worth a shit without pictures. but i expect that coming from you.

You could go ahead and start disassembling and cleaning.

well yeah worked a couple hours last night pulling the HX from the engine (fucking hose barb to MPT fitting on block caused all kinds of grief).

That is a maze of parts
6/1/2011 9:55:19 AM
The hardest part was keeping the springs matched with the corresponding valve pistons, as well as remembering which got switched out with replacements from the shift kit. I will say that the only parts I had left over were the (3) check balls that were required to be left out for the shift kit!

The "Fire Hydrant"after two months of trying to order the damned Derale pan, I let go of that idea and ordered a Hugh's Performance +4qt cast aluminum pan:Started assembly on my shifter tonight, only to realize that the linkage for a TF727 will not fit the case of a 518 due to the extra provisions for OD. Luckily the shifter has the same stroke as the stock gear selector on the transmission, so after verification that the gear detents match (hopefully), I will fab a bracket that attaches the cable directly to the shift selector.

I failed to mention last summer I popped off the timing pin nipple in the injection pump, and it fell down into the timing cover... I nearly had it, until i knocked it into the oil pan... good thing for screens on oil pickup tubes
6/2/2011 9:51:00 PM
what is wrong with the linkages? the only difference the 518 has is the electronically activated o/d (tps activated I believe). I used the stock 727 gear selector cable when i swapped to the 47rh.
6/2/2011 11:21:23 PM
Factory Selector Arm:Winters shifter linkage assembly:It's a 4-bar setup that transfers the motion 90deg to allow the cable to mount perpendicular to the transmission, under the tailshaft housing. I've shown it overlaid on top of the factory selector - you can see the rear bellcrank part will not mount due to hitting the casting bulge where the TC/OD solenoid connector protrudes.
