There are some things in life that are worth the wait, and the new transmission controller from Powertrain Control Solutions is that kind of thing. A novice will get lost in all the functions it and the new software have to offer, but for a PCS dealer like me who has wanted more in an aftermarket transmission controller, I am thrilled.
Rush jobs clothed with glitz and glamour are exciting but disappoint. However the meat in this setup has a lot to offer so that a whole new level of aftermarket control is now possible. Just a few of the new options are adaptive shift quality functions, calculated torque, Calibration B for clutch to clutch controlled transmissions like the 5R110, and a fully sealed and compact housing with an OEM type of wire connector.
Due to the high level of capabilities this controller has, PCS has chosen to leave the calibration development for most transmissions to their dealers and for that reason it is not available directly from PCS. The learning curve is indeed steep, and my application for it is still a bit rough around the edges, but with a few hundred miles already on my own 68RFE swap with the 2800, I am becoming the expert I need to be to sell and support this controller well, and I won’t stop until I have arrived.
I’m sitting in an airport waiting to get home after driving my own 68RFE swap to Idaho. I latched onto a loaded 2o’ enclosed car hauler there and finished pulling it to Phoenix AZ. My Dad will pull it back to Montana next week. Pretty hot down here- and my trans would get a little hot when going slow down here in the heat, (the 94-02 Dodges could really use a better fan clutch system) but otherwise did well- although we could have used more power than the stock 97 12 valve on the hills.
I have another customer with a 4BT and 68RFE on the road, and the type of tuning that allows Calibration B to be used seems to be working well with all the transmission swaps out there so far. That is giving me more confidence that this type of tuning may work with all 68RFE transmissions, and possibly even better than the clutch to clutch type of tuning that I have used from the start with most so far. That is good news, since Cal B is a mode that can access a totally different shift and lockup schedules, line pressure chart, and etc – making the Cal B function great for a tow/haul mode!
I have one more customer that has finished his swap and is on the road, so that makes a whopping 2 guys other than me running one so far 🙂 . It’s a 4bt Cummins powered Chevy Suburban. His trans is running pretty well with the type of tuning that allows Calibration B to be used – I’m still doing a little fine tuning on it, but I am pleased with the progress.
I will really try to get a you tube video uploaded showing me going back and forth between normal and tow mode (cal b) soon.
I have several other guys out there working on projects and will do an update when another gets on the road.
I’ve noticed a few guys wondering how the 68RFE stand alone control system is progressing. This will be the place to check for regular updates.
It is available to purchase, but there are a few disclaimers involved because so far there is only one other guy besides me out there that has one on the road. That owner lives in Canada and has the 68 behind a 24 valve Cummins in a Chevy pickup. He has in the neighborhood of 450 hp so he knew he was definitely going into uncharted territory when he decided to do the swap. He somehow lost reverse in his original trans – and long story short, we both learned a lot and he now has a stronger transmission and stronger tuning than what he had previously.
Other customers have purchased the system but their projects have not progressed to the tuning stage yet. The very first purchase is planned to go into a Suburban with a Cummins. At least two are planned to go behind 4bt Cummins, and two more into a Ford Cummins swap.
I have intended to get another you tube video done showing the Calibration B feature working- and want to get that done soon. The holdup has been taking care of current customers and Allison stand alone development. Cal B will allow a switchable tow/haul feature- as of yet I am not too confident it will be available to all customers- it depends on how each individual transmission tunes up with the normal type of tuning that does not allow the cal b function.
