Truck shifts like crap on tune...didnt before

[BLFX4K]

So at 30,000 miles I had my 30k service
Truck felt great, shifted awesome, mileage improved and I was happy

At 32,000 miles, after my highway trip to cali and back to Vegas problems began. The truck began shifting really hard and feels like its on the verge of failing, this happened after a program to level 3, was set to the appropriate timing as I was using 91 octane, not 93.

Yesterday, at 34,500 miles I replace the battery. Put in the new one and she cranked right up, on the stock tune, shifted blissfully, smooth and not a jerk or thud into gear.

Retuned the gryphon to level 2 and problems started again. Is there an update I'm missing or corrupt file in my tune that's causing this to where I should flash the programmer again? Have not updated since I got the programmer, back in July of this year.

Shift levels are at 0-0-0

Still shifts hard into gear unless I'm shifting at 1500 or less rpm and only does it on the canned tunes.

Any help would be great

Have you tried the level 1 (tranny adjustments only) tune? Did it give you the same results? I dont think there have been any significant updates since then but I seem to remember a similar issue a long while back.

Also, can I get you to fill out your userCP more fully? Only us mods can see the information and it would be rather helpful.

Haven't had a chance to try the level 1 tune, ill give it a shot tomorrow when I get back to my truck. Left it when I went out of town and left the keys at my parents. Got back to mine and have my spares so ill check it out when I start up tomorrow.

userCP?
Not sure what that is but maybe this will help:
2008 fx4 screw w/5.4 and 3.73 gears and 34700 miles
35" tires (but keep in mind it only shifts hard on the tune, not stock file)
OBX Longtube headers w/resonators and true dual exhaust
2010 efans
Gryphon on canned tunes

Not sure if it will lead you to your userCP but here is a link (might attempt to send you to mine which wouldn't work).
http://forum.gopowerhungry.com/usercp.php
If it doesn't work, scroll up to the top of the page, under the PHP logo, there is a dark blue bar. It says stuff like User CP, Members list, video arcade, search and log out. You'll need to add stuff like the HEX code of your truck and other information.

I notice that you are running on 35" tires, did you adjust the tire size accordingly for those tires? I've seen some trucks get really crappy shifting and stuff because the tire size is way off from what is actually on the vehicle.

Tire size is set for 2709 which is equivalent to the 35s and I believe a 3% squish factor.

I will add the HEX codes and other information come tomorrow. Will get back to you asap. Thanks!

Chris, follow this link: !profile to your "UserCP". It's where you post information about yourself that is mostly hidden from anyone but us Mods and the Administrators.

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:hmmm:

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. :yikes2: (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...:cursin:

[Longshot270]

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

[Jackpine]

Longshot beat me to it (damned younsters :D). Do what he says.

It really sounds to me like a problem with your transmission install, as you said, rather than anything a programmer did. (And I know Bill is rather "conservative" when it comes to tweaking the transmission because he wants it to last.)

Exactly why I think it had to do with the dealer and the failure, it happened not 5,000 miles after they "serviced" it. The problem was noted around the 31,000-32,000 mark with the crappy shifting and I am taking it to a different Ford because I am afraid it will happen again.

Cable and tune has been removed. Do I HAVE to drive 50 miles or just say the battery cable was disconnected overnight to see if the problem went away; to ensure the P1000 code I believe it is, is not stored in the PCM.

Praying to the Ford gods that they fix it under warranty:hehe:

[Longshot270]

Jack I aint so young anymore...I'm a year older than I was a week ago. :hehe:

I think it would be better to drive around to get rid of the code. You can take the programmer along while you drive and periodically check to see if it is there. The programmer can be used to passively monitor the truck.

[BLFX4K]

Truck is at ford

The tech drove it around for a few minutes to see what was wrong

He came back around and cruised through the service department..."no reverse?!":giggle:

Waiting to hear back from them tomorrow to see what the final verdict is

[BLFX4K]

Turns out something in the truck is shorting the pcm/trans

Ford says its fixed and I am about to go and find out. Will take it for a drive and put the tuner back in and see if it shifts the same

Does PHP offer a program through the mac computers or just windows? My pc died a month back and still waiting on a replacement drive with operating system

[ticopowell]

Just windows... but its a small program so find a friend with a working pc, ideally with windows xp still, and install it there :)
