I haven't installed either yet but I have the transgo jr and I also have he transmission tune that came from PPEI on my autocal.
Is there any problem or concerns with using both? Any thing I should know about?
I thought since I'm adding some bolt on mods and EFI live, that the tune would be beneficial? That was my understanding from PPEI.
That's also why i bought the transgo jr.
A tuned TCM helps boost TC line pressure...so does the TransGo Jr...it may be redundant but I have a friend who did TCM tuning on his '16 High Country with EFI and it's night and day difference from stock setup...granted, he's not rocking a TransGo Jr...it felt and performed much more crisp shifting and flawless transitions in shifts (I realize the new trucks have much more developed TCM tunes and power outputs). I'm curious if there would be a similar benefit on a LBZ/Allison 1000 combo WITH a TransGo Jr...I know this seems to be a rhetorical inquiry that I may have answered already, but is there anyone with the LBZ platform with TCM tuning that can chime in?
You don't tune the 01-10 trans for bumps in line pressure, that is done in the pump by either adding the shims or different springs or both. The transgo jr helps the 4/5 and 5/6 I believe as they are of and are more susceptible to slipping. That said you don't need tuning to put a transgo jr in a lmm. Just install and you can relearn the trans or you can run it through the gears easy and get more thottle input as you go thrush more times
Minerigger, thank you for the clarification on line pressure...would it be prudent or worth trying a TCM tune on our OBS trucks even though a TransGo Jr has been installed? Do you believe there woudl be any increase in getting the power to the ground or would it be just "pillow-talk" from a reseller of such tunes?
