Truck shifts like crap on tune...didnt before

[BLFX4K]

Just updated the UserCP

Tuned it to the level 1 tranny only and it still shifts hard into gear, sort of like the edge on levels 10-10-8 did but more of a dropping feeling, not a firm shift. Hard to explain.

Again, the transmission only shifts like this on the tune, not on the stock file


Thanks again fellas

Does "dropping" mean it feels like the power is being reduced during the shift? If so, that could be a problem in the torque reduction strategy that is employed during shifts. And, I suspect Bill could change this for you.

The dropping is more of like something dropped out the bottom of the truck or it fell into gear.

Its a slow hard slam, does not feel like that at open throttle or on the stock tune

Sorry, I can't even imagine what you are describing (and don't take that as a "put-down")! I've simply NEVER felt anything like that, EVER, in all my 54 years of driving. (Has it really been that long?)

This is something you really need to discuss with Bill, I think. Make sure he understands the shift is "normal" in the stock tune.

I don't blame you it's kind of hard to describe :/

When it shifts above 1500 rpm it's like a slow hard shift into gear, like rough enough to make you think the tranny is failing or going to fall out. It doesn't move you physically but it can be felt through the pedal and the truck itself, I pay close attention to her to make sure she's running 100%.

I'll be driving and at 15mph it goes from 1-2 and it feels like it slams into gear. Not a smooth shift and not even a firm shift that is felt when you bump the firmness settings up.

Just leaving it stock for now and filed a ticket/claim on Friday. Hope to hear back soon

Well today I lost 1st and reverse

2nd, 3rd, 4th and o/d all work

Just flashes, whines in reverse, no movement, whines in neutral

Goes in the shop tomorrow or monday

Hoping ford covers this under the 60,000 mile powertrain warranty

The ford who serviced my tranny at 30,000 I would believe is the culprit, turns out my friends f150 who was serviced at the same ford went through 3, yes three, transmissions at that dealer in 80,000 miles...

That is not fun. You need to program back to stock and remove the programmer, cable and everything associated with the programmer. Otherwise they could wiggle out of covering it.

Good luck
