Torque converter sliping anyone ??

I almost never fully lay into my truck its more of a tug boat than anything else but I realllly really got into it today smoking a duramax literally and figuratively getting onto the freeway I swear i saw my Insight say 110% load haha and when I got up high like around 80-90 it had like a deep shudder/vibration going on maybe it was just the truck saying slow down cuz shortly after my Insight started going nuts and blinking 1350 at me so I back off. Some times when im towing heavy I don't really get into it till I feel it engage into 2nd and sometimes 3 and I can feel the torque converter slip a little is anyone else getting similar stuff or do I need to call RevMax and get a trans built ??

My buddy has a 2011 and is saying the same thing is happening to him. Ford gave him a price of 4100 and no one around us is building 6r140 yet.

I've noticed my tc will lock in 3rd around 1500 rpm not ripping. Butttttt if I'm in any gear with it locked and i start ripping it will unlock an if i start ripping before it locks it will go through 6th and still not lock till i let off.

I would talk to the folks at ATS....Seems like they're on line with our trannies. Looks like they have a high quality converter. I looked to see if SunCoast offers anything...they go up to 2010.

Here's a link:

I think these trans are supposed to be pretty stout as it is. I would just look at getting an upgraded torque converter and save yourself some dough. Ive seen a few companies listing upgraded TC's for under $1000. Cant remember where though off the top of my head.

I've noticed the same thing. I had a triple disk TC with billet cover in my SunCoast Stage 4 Allison. That thing would lock early and sure felt like it stayed locked. Not sure if such an upgrade would expose other weaknesses in our driveline. I haven't read about people smoking frictions like we did in the early years of the Allison....Hoping Ford did in fact over build the internals. Guess more time will tell.

Oh I have no doubt the trans is very good I like it more than the 6 speed in my past few Cummins trucks and I haven't had a stitch of trouble with it, it was a one time thing and like a said it didn't even really shudder till probably 80 it could have been bumps in the road for all I know, the only other time I feel it " slip " is getting on it as soon as it shifts into second I hate first gear launching because it is sooo short so I don't really lay into it till 2nd and I can feel that faint shudder through the whole drivetrain which in the dodge world was blamed on the TC.

I hear ya, I came from a 1/2T dodge and my work trucks a 2.5T cummins and both auto trans are horrible. I was set on never owning another auto trans but ive been surprisingly happy with this 6r140, driveability is way better! I havent seen much out for these trans but something simple like line pressure boosters might solve a few smaller issues. I put a shift kit in my 1/2T trans, didnt make it amazing or anything but deff noticed a good difference in shifts and lockup. I looked on transgos website but nothing for these trucks, maybe ill email and see if they have anything in the works.
