I have a 2007.5 ram 3500 that I have recently purchased.

[Parts list]
Arp head studs
Built 68rfe transmission
Edge tuner
Egr delete
Efi live
Just to list a few

So I just installed the bd transmission pressure controller[p.n.1030369] and want to know.
Can you use with out doing a relearn. If so what do you think would be the best way go about driving with out relearn procedures. Also the risk of no doing a relearn and best outcome?

I want to add talk to a bd tech and sales rep. They say you can giving that you use less the 25% throttle,watch load values,drive 50-200miles limited to a max speed of 55 or 60mph changing throughout gears 1-6 and will be fine.
How ever I have seen many post about transmissions not shifting or being in limp mode I live 200 miles from the next shop. Can you please give your thought on this info help would be much appreciated

subscribed. i have the same question regarding quick learn procedure, just rebuilding and installing my own trans atm.
I have read a few forums and everyone says that you have to use a scan tool to perform the quick learn procedure.

A retired dodge mechanic told me that i just need to leave the batteries totally disconnected overnight or do a capacitive discharge by disconnection the batteries and holding the positive and negative battery cables together.
Can anyone confirm this will work?

I also found these instructions and was wondering if i need to do the drive learn procedures on page 9, and then i should be good to go...?

Jeffs2cummins after talking the the guys over at bd I was told if you don't use a scan tool or do a relearn you can drive if you do the following.
1. Drive 50 miles going through all gears 1-6 repeatedly
2. No more then 25% throttle and no faster then 55mph
3. If possible (with tuner) watch load % not letting it exceed 25%,have a line pressure reading on your tuner watching for spikes and how much the number changes from your base reading
4.after 50 miles no towing, racing or pulling with your truck for atleast 400 miles so basically drive like a grampa.
Otherwise then that I just completely 80 miles of drive time no problem shifts are solid no more gear hunting but like bd told me be mindful that it take a bit for the part to work as it should.
I hope this helps

Thanks for the update.
I also got a response from TransEngineer. Below is what he told me. What i can see, is that the quick learn is a recommended thing to do, but not necessary if you do the drive learn process that you explained above....


TransEngineer
TECH SPECIALIST

Disconnecting the batteries is not the same as a quicklearn. I'm not even sure whether disconnecting the batteries will affect anything, although I worked on transmission hardware and not on controllers, so my knowledge is limited. Still, I believe CVIs and other calibrations are stored in non-volatile memory, and if that's the case then disconnecting the batteries won't change anything.
A quicklearn actually runs through a routine that applies each clutch and sets all the CVIs based on the response that is seen. So even if disconnecting the batteries did put you back to the default "factory" settings, that would still not be the same as running a quicklearn.
Now having said that, you can also "drive learn" the trans if running a quicklearn is not an option. Simply drive the truck GENTLY for the first couple hundred miles. That should allow the CVIs to learn to reasonable values.

I figured as much I know there was alot money thrown in to this truck I don't want to throw another 6k for a built Trans.
All n all the bd 68rfe pressure controller was an easy installation took about 15mins to install over all very happy with it. Time will tell but I do feel a difference when shifting no shuttering,hard shifts or struggling runs through 1-6 now with no problems

With the paperwork on it and talking to the p.o and the shop its needs higher pressure due to the Trans being built. It needed to be replaced that is all.[/QUOTE]

Yeah if you need higher pressure then it would be worth looking into. I would look into if you need higher line pressure for your Trans
