Anyone? :confused013:
Smarty Jr. Questions..what to do?
2534
13
I have a smarty Jr. on my auto 48RE. I have had my truck in twice to fix the common hunt shift. When my truck Is set to STOCK, the tranny shifts great. But when I set the smarty to “FUEL ECONOMY” or “TOWING”, my tranny goes back to that dreaded hunt shift at light throttle. I can power through, but would rather not.
I also have never updated my smarty and have one of the original versions-whatever came on it in the box.
Do I need to update the smarty?
If so, what settings are suggested as far as the timing/torque management?
Will this even help my problem?
Will I lose the “added power” adjusting those levels?
I guess this part doesn’t really matter, but will I lose my ability to roll some coal with the updated versions?
Thanks guys, i appreciate it.

I dont think updating the smarty will do anything. Do you know what they replaced in your trans?

I assume you have a stock valve body. The smarty increases the line pressure causing the gear hunt. I just ordered the following, it claims to fix the issue. I hope to have it installed in the next couple weeks and will let you know.
Dodge "RE" Governor Solenoid to GM
Pressure Control Solenoid Conversion Kit
#REC. This kit was specifically designed to handle higher base pressure in high performance applications and to improve the reliability of the governor solenoid in normal use. In performance units the pressure can flood the Dodge solenoid and cause a no shift condition at full throttle. This is the fix. Fits all rear wheel drive RE model transmissions. Added 9-25-2008. Cost $149.00

Replaced VB and rebuilt TC, governor pressure solenoid and a few other things.
But like i said..it shifts/drives perfect W/O the smarty. Once i download the programmer, then it shifts retarded.
This is why im wondering if i need to update my Smarty to a newer version.

So even with all the aftermarket tranny stuff you've got, you still have the problem?
I would, though, like to hear your thoughts on that part when you get it installed.

I still get the tranny hunt with light throttle. Its annoying because Im trying to stay off the pedal to get better mileage. From what I have read, the stock governor solenoid can't handle the higher pressure the smarty and other programmers add when they ajust the stock torque management program . Hope this works and Ill post the results....

Mine actually shifts better with the smarty-jr than without. Doesn't gear-hunt as much, shift points are higher in the RPMs, and when needed only drops down one gear when pulling a grade rather than dying in OD then dropping two gears like it did stock. I have the 5.08 version the software. Software upgrade is free, certainly worth a try.

Set the Timing to 4 (which should be similar to what you have now) and romp on it, yeah it will create a nice cloud.

The Smarty does not increase line pressure. These tranny's are not ECM controlled. The only way to increase line pressure is to make a mechanical adjustment or install an after market V.B.:thumbsup:

:S:Just trying to get my brain wrapped around this issue:doh:....So the programmer(smarty) increases the demand on the transmission with the extra torque, but the lack of increased line pressure is causing the shutter shift? or where is the connection? I had the same issue w/ the DiabloPredator. I figured my BD/VB would solve this problem. I have already replaced the Governor pressure soleniod and sensor trying to cure the issue. It would be nice to find a solution other than going back to stock.....stock isn't as fun:headbang:
Maybe its more of a throttle position to speed issue? with the smarty or other tuner that increases power, less TP is required to gain MPH. Maybe its causing the tranny to go nuts? i dunno. My 05 does the exact same thing as you describe. Stock is great. load a tune here comes the stupid shifts. I switched to a juice attitude set up (something that doest effect ECM at all) and problem went away. My superchips flashpaq and smarty jr both drove the tranny nuts. Just my experience tho.
