Converter unlocking issues
I recently installed an ss4000 converter and am having some unlocking issues with it. I have the ECT temps high enough so that misfire detection is off yet it still unlocks. Any ideas?

Are you using HP Tuners? If so, you can adjust your throttle position for apply and release. I think my 3,200 is set to only apply in 4th gear.

I currently have it set to only lock in 4th gear and it is supposed to only release at 42 MPH but I have random unlocks anywhere between 55-70

Sorry, yet I am using HPT

I think the table I was looking at is percent throttle... not mph. I use HPT as well and would be happy to compare settings. On a long downhill about a mile from our house, I will get a lock/unlock that is somewhat annoying as it just happens to hit every time. I pull the shifter back into drive and this avoids the issue. Kind of a cheap fix, but that is the only time I have had an issue with ours.

Right, the table is TPS vs RPM but the values you enter are in MPH.
This is probably the table you are referring to right?

did you turn misfire detection off in all 3 ranges? Like was stated....make sure your lock/unlock tables are correct. You need a little buffer there....like 3 mph I think. It's been a long ass time since I've done any tranny tuning. I'll have to dig my laptop out to look at my tables and see what all I have done.

Misfire detection should not even come into play since i have it's min temp set to something like 265. So that should be completely disabled.

I think I have 2-3 mph between the apply and release. Had a long day working outside yesterday and was kind of beat when I read that table. You are correct, the table is mph.

I think I finally might have an idea as to what is causing the issue. Usually the converter won't lock back up right away if I take my foot off the gas, but recently I have found that if I tap the brakes, boom it locks right back up. So I contorted myself under the dash and played around with adjusting the brake light switch further away from the brake pedal then all the way flush with it and neither one really made a difference so it could be that the switch itself is faulty. I've put in an order for a new one and once it arrives I have my fingers crossed that it will finally put this problem to rest.

I use the brakes on the hill, but never paid attention to the effect on lockup. I think the speed window in the tune is kind of narrow and that just happens to be where I am at going down our hill.

The effect is not there when using my brakes so I think it is tied to that. Or I am hoping. If this switch swap doesn't fix it I will be at a loss. And I would hate to give it to the stealership. The last time I did that for a blinker not working cost me over 400 in electrical work by them

Ugh. My car only sees the dealer once a year for an inspection sticker... and that is one of my friends at a local Ford garage. If you need schematics or anything, let me know. I have the factory manuals for our '02 - should be the same as yours. Be happy to look up anything you need.

Hi, I think I'm having a similar issue. I posted a video of my tach in this thread in General Help:

What do you guys think?
