Ok so got the Dunrite valve body in last night. Made it a whole new truck, can't believe the power that now is on tap. Here is the problem though, I have no 3rd or 4th gear. Anyone had this problem on a 47re valve body swap? Any suggestions? TC goes in tomorrow.
 
Did you add a resistor to the governer/ecm wire to keep the computer from seeing the higher pressures? I've only heard of it affecting 1st gear--but could be? Have you called dunrite?

Fwiw, installed my dtt valve body a few days ago and have had no problems at all. :flipoff2: Still need to do the tc as well.
 
No 3rd or forth could be many things. Can you get your hands on a scanner? Or at least see if there are any engine codes or anything in the freeze frame. If you can get a data display that would be great.

I just need some more info. can you shift it manually into 3rd or forth?

I really had no business installing this thing myself. I put the resistor in as per instructions. Did everything, but it looks like something is wrong, according to the chrysler service manual and th shopkey it may be a govenor problem or a stuck plunger for 3rd gear. Dunrite will for sure get a call for help on monday but since I didn't get the vb in till last night around 9 it was to late to call for help. :beer: to you and your damn good luck.

I'm getting the scanner out tomorrow since I got a buddy to help, I may work in the shop but have no idea what toys the mechanics have but he says it will scan the codes and everything else the system records. I can't manually shift into 3rd or 4th. According to the service manual it won't go into OD if it can't first shift into 3rd so I believe it safe to assume it is related to 3rd. When you drive it shifts 2nd and tachs till you let out of it around 3200, let out of the throttle then seems to jump into neutral and once the rpms and spd go down it shifts into 1rst and tachs at around1900-2000 and throughs you into the dash in the process.
It'll sit till I figure out what to do so I don't run the risk of burnin anything up. Got a buddy that is a chyrsler master tech with lots of trans training that if I can get ahold of him can help hopefully. I got his service manual for the trans so surely he will answer my calls soon.
 
That sucks man. How long did it take for you to install? It took me over 6 hours by myself. :rolleyes:
Fwiw, I have read of other people removing the transmission relay (in the relay box next to the batt) so that they were able to manually shift to 3rd--though, not into od--after having upshift problems. If that works, the problem will be tied to abs/vss sensors or governer. Might be worth a shot?
 
So we hooked up the scanner and found a 3rd gear shift command not met or something due to over rev or some crap. Cleared the code and the thing shifts great. Dropped almost 200 rpms at 65 mphs to. But the greatest thing is how firm and smooth the shifts are but everything is over shadowed by the instant throttle response and insane power it allows the motor to deliever without the chip on. I made a bigger difference than the chip on 45 hp feels like it on 75 but with instant response. I LOVE IT. Thanks for all the help.
 
Glad it worked out for you. My old psd felt alot stronger after I did the valve body in it also, wait till you get the tc in and it hits lockup, hold on. When I first put the valve body in mine, when it hit second gear, it chirped the tires. Not bad for a 130,000 mile factory auto.
You should just scrap the auto though and swap in a 6spd.:lol:

Only if you swap IN a 6 oh no.:flipoff2:
 
Uhh, nope. that's just not possible.
Uhh, Yep. What else do you call going from 2100 rpms at 65 to 1900-1950rpms at 65? Besides the master chrysler tech buddy of mine wasn't suprised to hear it , and Tony at dunrite told me to expect it, you know the daddy of valve body's for RE trans and the father of triple disc converters. I'm not going to argue with you though, cause it is what it is wheather you think you know otherwise and the bottom line is it is the best mod I've done so far and recommend it to anyone. I did service it and adjust the bands and replace some solinods. I wouldn't write that off. I say it was bunch of things.
And no to a 6 spd, I love my auto again. :flipoff2: Now on to the nightmare of the TC install.
 
ASSuming your TC was locked up before, a valve body doesn't change your gearing, which is the only thing that will change your RPM's.

If you like the valve body, you're gonna LOVE the TC & VB combo..

Your right, I spoke to Tony for clarafication before I put my foot in my mouth and he said since I described the lock/unlock over and over in overdrive then like most 02's my line pressure was just to low and that was wearing the engage solinod out from excessive use so he suggested I replace it while the pan was off. Since my pressure is up to a reasonable level thanks to the vb and the TV cable is now adjusted I was able to lower the operating rpm in OD thanks to the lock up now working properly. So braxton your right to, my OD was never really working or at least correctly.
Anyways, forgot to ask him how much fluid the TC will hold and if it is ok to replace one of the presurre test port plugs with my tranny temp probe. Any suggestions?
 
Here's how I installed the temp probe that comes with the juice/attitude. (page 25) http://www.edgeproducts.com/product_images/product_variation-user_manual-143.pdf

And according to DTT's install instructions, if you're just doing a VB--add 9-10 qts, if doing vb and tc at the same time it's 15-17. I usually put a qt or so in the tc before installing it, but I need to read up on the 47re install some more.
 
Got the TC in last night and whoa mommy, that made it a new machine again. Don't want to put another one in anytime soon but man it was worth every penny. They should have come from the factory that way. Can't get over the difference it made. Anyone looking for a way to improve their truck this is the way, not that chip isn't good to but this is much better.
 
Any tips on installing it? How long did it take?
Yeah, find a trans shop to do it :flipoff2: We had a four post ramp lift so the truck was up high enough to walk under, a nice trans jack they use on the medium duty truck trans, a 5 ton port-a-power to spread the frame back out when we removed the trans crossmember, and my buddy's 30-40 grand in snap-on and mac tools. It still took 4 and half to 5 hours, granted we had never done one of these but it was still a royal pain in the ass, the worst parts were 1) the hard steel lines of the cooler are always in the way, just completely unhook them trust me 2) the tc line up and slip in to the two sets of splines and then getting the pump to engage, mark the drive on the tc and turn the pump teeth up and down and take your time 3) the frame closing together over an inch when we removed/drove the trans crossmember out, then having to port-a-pwr it back apart to put the crossmember back in. Everything is 14mm, 15mm, 16mm, 18mm, 19mm and have at least 2 ft of locking extensions just to get the tc bolts out. There is no way I'd try this without a lift and trans jack and some way to spread the frame, my buddy said the frame thing is worse on fords.
 
how much do these new valve bodies cost, and who makes the best one?
I think they all run around 450 plus a 100 dollar core. The best depends on who you talk to. I went with dunrite cause he is the daddy of the dodge valve body rebuild/upgrade. He has been doing it the longest and builds the vb to your specs when you order it not pulling it off a shelf. He made a good point none of the others made to. If your not making 600+ hp while you drag race or sled pull you don't need a 4 grand tranny or billet this chrommoly that, or new billet flywheel or any of the other crap they all want to sell you. All you need to tow with is 350 hp on the ground and a vb and tc built to your specs and change the fluid on a realistic interval. Shop around and realisticly decide what your goal with the truck is. Then get it, cause it really is the best upgrade I've made, far better than a chip, plus now that I have the TC in, it is unreal the difference the two made, it pull like a manual but no clutch in traffic or headaches on hills.
 
my DTT valve body is built to spec also. He's not the only one.

If you just want to tow mild, don't mind unlocked shifts, and are SURE you'll never go higher HP, then a TC and VB will probably serve you well, assuming the rest of the trans is up to spec..

But there's plenty of reasons to do other upgrades, it's not just 600hp sled pullers that need 'em. example: try to get it to shift firmly, and you can crack the plastic OEM accumulator over time. shift with the TC locked, you can pop the input.

YMMV.
 
Installed my TC tonight by myself on the ground. Honestly, not quite the PITA I was expecting...but maybe that's because I was going into it expecting it to fully suck. Took probably 9 hours. Too bad it's raining :rolleyes:.
Anyway, thanks for the tips superpile.
