2010 Ram Hemi Tranny Jumping And Rough

[Ramathorne]

I have the latest update for my U7137 for my 2010 dodge ram hemi, and now when cruising along and you floor it jumps/sputters/shakes (its like its confused at which gear to hit) and after several seconds it finally kicks down to first as it should???...Seems like it would be quite hard on the tranny?

It didn't do this before the update...

I have tried 91 and 93 tune and both do the same

[Ramathorne]

OK will try that today
Thanks Mike

[Ramathorne]

Tried it Mike

[mikel]

restoring the stock tune makes it go away?

[Ramathorne]

Yes it shifts fine at WOT with stock tune

I have never seen or heard of this from anyone else, not sure.
Try updating to 9r09.

I have just updated and installed the 91 octane tune on my 2010 Ram 1500 and I had it do the same thing today. When you hit the loud peddle to pass it shudders. And I find the old tune had more jam off the line just feels that way to me.

I have a similar issue on a 08 Ram Hemi. When cruising at 65-75mph and I hit the gas to pass, the trans shudders before downshifting. It's like it tries to hold the gear, slips, and then downshifts. When cruising at 45-60mph and I hit the gas to pass, it downshifts immediately like it should. I am currently running 9r09 with 91 Tune and MDS disabled (no other adjustments). It did the same thing with 9r07 and 9r08 but not with the stock tune.

[mikel]

can you guys post up your last tune written?

[fitter1]

U7137-9t09e.crom. That is what I updated to and it shuddered. I was reading another post last night and down loaded the 9t09d tune you posted for the 09-10 Hemi and no more shudder.. I'm new to the tuner thing and my wife is amazed I can figure this thing out.

I hope that tune is for the Ram 1500 4x4? The post I was reading that's what the other guy had..
Any help would be great... Thanks!

Modified stock tune with advanced features was the post I read! Thanks.

Here is the last tune written to my 08 Ram Hemi.
