H&S tranny problem

[Powerstrokin250]

I have the xrt pro and i have noticed this happen a few times... When im on it hard from a dead stop it seems to slam into 4th or it might be 3rd tremendously hard and it cuts the power down to the engine for a second and then picks back up!!

Any help is appreciated.

did you just install it? what software version are you running? what trans software?

Mine has did this a couple times as well. When I was driving through town and got off the pedal, then tried to give it a little and it felt like it was in neutral, then shifted into gear all of a sudden.

Probably just have to give it a try & see what happens. How long have you had it installed for?

I'm curious about this too. I'm still running the sannes tranny tune while running my 250 tune. Overall, I like it.....However, the 4th gear lock-up does become a pain in the A$$.

I think with S1H it locks up a little later. Maybe try that.

Ive had it for about a month... I had to send it off to get it fixed becuz it would shut itself off during programming, so they are doing an update to hd 300 and they installed the s2m file.
