I'm pretty sure this would only change how overdrive operates though, since I think these transmissions still use a cable to control the other shifting. Not sure what these 'enhancements' are though. It says that all levels on the programmer provide 'enhanced transmission tuning'. As for adjusting shift points and all that, it doesn't let you do that manually either.
Not sure why this is, but I know that it isn't an option on this application. It doesn't do gear changes for some odd reason though. Well, before you guys burn me at the stake over the price, I picked it up for only $200 shipped on eBay!!!:flipoff: Couldn't pass it up for that price. I'll keep you guys posted on how the performance changes, and also if I use the other tuning levels. I'm pretty happy with it, just for the fact that my speedo is now correct and also that I can now read codes too. Hopefully I'll get a chance to try the Premium Tuning and/or Towing Performance levels out soon.īoth of those require 91 octane though.:wall: I was kinda bummed that I couldn't do any adjustment of shift firmness and shift points like we did on my cousin's truck, but with a Dodge trans, that is probably a good thing.
I could feel a difference in how it pulled in the upper RPMs though. Didn't seem to make much of a difference on the butt dyno, but I did only do the minimal tuning level.Īlso, the weather is kinda crappy here tonight, so I'm sure the humidity and temp aren't ideal for comparison either. Anyways, took a quick trip around the block after installing it. Not sure about the other code, but I'll investigate more. I know why the O2 code is up there is because of my damn O2 simm (must have gotten wet or screwed up).
I ended up having a P0138 code (1/2 O2S Shorted to voltage) and a P0783 code(3-4 Shift Sol, No RPM Drop at Lockup). I only installed the 87 octane tuning level on it, raised the rev limited, raised the speed limiter, and adjusted the tire size. Didn't have as many options as the one on my cousin's Chevy did, but such is life.
It took a grand total of 5 minutes to do. I just installed the Superchips Programmer on my truck.
