I just replaced all the internals in my whole 47re with the exception of the shafts and gears, all the clutches ect. were replaced with the BD "stage 3" heavy duty kit. the valve body was replaced with the BD Valve body, and my converter was replaced with "Diesel Performance Converters" super single converter. I had a local shop do all the work. But i took the trans out and put it back in. once the whole trans was bolted up and filled i took it for a spin, the 2-3 shift was real hard, so i adjusted the TV cable up by the throttle on the clean side of the engine. now the trans shift awesome from 1-2 and 2-3, it shifts around 2,000 rpm. the 3-4 shift takes a little but it does shift with out and difficulty, the problem I am having is that once i'm in 4th which correct me if i'm wrong is known as Over Drive. Truck will tack up as high as red line and will not go past 60-65 mph. It sounds like the truck still has one more gear too go, but it is already in 4th as i have counted every shift. I have not checked any sensors only because I cant see a sensor causing this problem. Is it the valve body? Am i missing something while adjusting the tv cable? i'm at a loss. is it the converter? i have no clue how to feel if the converter is locking or not locking. It might be a little hard understanding what im saying but i have no clue how else to explain it.

In simpler terms the truck shifts fine from 1-3 but the 3-4 shift takes a little long and once in 4th gear my truck feels like it im driving a combine very slow and high rpms, the truck use to top out at 95mph with the rpms low.


any help would be greatly appreciated, my only move after this is too put the truck in the shop and which Christmas coming up i don't need that bill :banghead:

Ok you are saying that you are feeling 4 shifts?..i would say you are feeling 3 shifts and the last one is the transmission going into OD. Think of it like this: when you are sitting still you are 1st gear then you take off and it shifts to 2nd. (thats your first shift). Then its 2nd to 3rd( thats your second shift). Next is 3rd to 4th which is the (Third shift felt), then last is OD kicking in, which normally is a 200-300 rpm drop from 4th gear. If in fact you are feeling the shifts like so then you are in OD and the engine is screaming and not putting any more power out throu the converter. I hope the transmission shop will back up there work. I would make sure they checked all the pressures, before you blame them lets try something. Im not a transmission expert but it seems that you may not have enough transmission fluid for the converter to function just right. the TC will seem to slip if it doesnt have enough fluid to hold the lockup...Please double check the fluid,before you start pointing fingers at the builders, after the transmission has warmed up, cycle throu all gears and leave in neutral to check..*parking break on* It takes 16qts to fill up the transmission and converter if they are dry. if you are over a 1qt is safe to. Trust me if your transmission is over filled it will let you know by puking it back up out the filler tube, dont ask how i know that*

How much "grab" does the tranny have in OD? If it feels mushy it could be your OD clutches slipping.

I just had my tranny built somewhat similar to yours and I sure can feel the converter lock up! Feels like the turbo lights again! Not sure why your tapped out though, but I think the 3rd and overdrive are electronically controlled...

Did you replace ALL electronics when built? I made sure that everything electrical in mine was replaced....

 

[dodge96cummins]

i did not have any of the electronics replaced. stupid me, i was going too buy all new electronics for the trans but then never got around too it. i defiantly cant feel anything lock up, prior too having the trans rebuilt i could literally feel the trans kick into O/D because the rpms would drop and the coal would start to roll... I don't get any of that anymore. as for the trans fluid, when I first filled the trans and took it for its first drive I had over filled it by a qt or so, my brother drained some of it out, the fluid was cold when he did that. he said it was right on the "full" mark on the dip stick, and now today when i took it for a drive it was shifting better then it did the day prior too having some of the oil drained, tomorrow i will warm the trans up. put it in neutral and check the fluid again. SAMURAI you are right about re explaing what i was trying too say, when the OD does kick in (4th gear) it does not put anymore power too the ground but the rpms are still screaming. the quy at the shop who built my trans said he pressure checked everything and his words were, "everything shift beautifully". is there anyway for the trans to be full on fluid but yet the torque converter could still be lacking the right amount of fluid to operate properly? im just still not understanding why the truck seems to be geared so low. I have nooo experience with transmissions at all.

 

[my_samurai]

Far as the fluid goes, if you have it on the OK mark by now i say its good. Theres a governer pressure solenoid and a temp sensor that control lock up..its possible that one or both did not get plugged back it, or plugged in well to make contact. I would find out if those were tampered with. I sure wouldnt keep driving it.

 

[crewcabstripper]

Are you sure your even going into OD? Shouldn't the 47re have shift points of 1-2, 2-3 unlock, 3rd lock, 3rd lock to OD lock? Your 3-4 shift solenoid may be acting up along with your torque converter lockup solenoid try dropping the pan to see if the harness or plugs came loose they are right on the side of the valve body any can be replaced in acouple hours easily hoping to replace all mine today if I can get some fluid to refill the trans with when I'm done

 

[len70]

i think your feeling the conv lockup in 3rd, it is not going into od(4th gear).

 

[dodge96cummins]

I can check all the plugs and see if they are plugged in right. im going to drive it up to the shop that built the trans today, the shops only about 10 miles from home and all back roads so i wont be going too fast. They told me too bring it up since they did the trans they will figure out the problem at no cost. thank you guys for all the help. ill be sure too let yous know what was the problem.

 

[crewcabstripper]

Sounds like they will make things right by the way it sounds hope they fix it and be sure to post what the problem turned out to be

 

[MikeRodrig27]

I would check for codes even if you don't have a check engine light.

 

[irish power mad]

I'm inclined to think your not getting into OD at all. If you were then the truck would go a lot faster then 60-65 red lining it irrespective of tc lockup. OD on these trans is controlled by a solenoid and it's here I would start.

 

[dodge96cummins]

ok guys, after what seams like years they finally got around too ripping my trans apart, the problem was 1. i had a seal leaking on the pump in the trans causing it too loose pressure when i went into O.D, 2 there was a very small pin hole in the "boost tube" on my BRAND NEW BD valve body causing it too loose pressure. 3. because of that little hole my over drive clutches were slipping causing them to fry. mind you i only had 30 miles on this new trans. now i am talking with BD diesel too get them to send me the new boost tube and clutches since the valve body is warrantied they should send me the new tube and clutches. hopefully i get my truck back before..... fall or 2013 at the rate this is going.... i will include a picture of the pin hole but i cant get any pictures of the clutches as they are still in the trans.
