Hey guys, browse here regularly but first post. I've had my 6.0 for about a year now (been around it since new though, was bought new by my employer). Done a few mods, fixed what needed fixing, but I am now experiencing some shifting issues that have me stumped. I had posted on another forum but got limited response, none that helped. Hoping you guys can give me some ideas!
Here's the scoop, my pickup with stock tuning has the infamous 3-5 "shift flare." It's a rare thing and happens at light throttle. It doesn't seem to be a clutch slipping but more just a laggy shift.
Tuned, I run SRL for my daily, 3-5 shift pressure upped 10%. I've been very happy with how this tune acts, performance and shifting. Should be noted I drive pretty conservative and will very rarely faintly get the laggy shift from 3 to 5, but isn't as prevalent as stock tuning.
Now on to the part that has me worried. I'm not a racer and have no desire for my diesel to turn over 4k, this tune was factory set at 4150 I believe, I lowered it to 3950. Despite my conservative driving on occasion I open it up to keep the turbo swept and any cobwebs blown out.:swordfight: About 3/4 throttle it will lag the 3-5 shift bad enough to hit the limiter then bang into gear, if you let it run through the all the gears near or at WOT it wants to do it at every shift.
Is it a tuning problem, maybe related to lowering the limiter screwing with the shift points? Am I experiencing hardware problems in the trans like a sticking direct and possibly EPC solenoids? I just want a more concrete idea before I throw money in my trans or start bugging Matt about tweaking the tune.
