So... these programs do away with the skip shift feature for the auto tranny? Hum.. interesting.

OK so answer this. When you put it in "2nd" with the shift lever. What gear does it actually use?

My stock 06 skips 2nd gear unless heavy throttle is used.. and when you put the gear selector in "2nd" it's actually in third. (Verified this by using autotap because a local 04FX4 guy told his did this as well)

i put mine in 2nd gear on the selector and it is in second gear......i have never heard of a Ranger skipping 2nd gear......you have the same tranny i have unless they changed the factory programing....

start off from a dead stop with the selector in D with overdrive on......that is 1st gear....count the shifts....there should be 4 shifts total and you are in overdrive or 5th gear....

^^^^^ Mine stays in second when I put it in second, ha ha ha, but mines a stick.....LOL....

On side note, maybe it is set that way for gas mileage, I know that my trans am had a skip shift program in the trans (it was a stick) that would actually lock out 2nd gear under light throttle and you would have to go to 3rd or 4th...... Just a thought. I fixed this by buying a skip shift eliminator.....

Yes they have. What year.. I don't know?

I use www.autotap.com on my lap top and have seen this first hand. I can also monitor the torque convertor lockup.. which btw feels like a shift.

When I put mine in "2nd" the tranny goes into 3rd.

When you put the gear selector in "2", it will start and stay in second gear. It is useful for starting off in snow. However, even with the Bama tune or stock, if you are taking off realitively easy from a stop with the selector in "D", it will usually start off in second gear anyway. You can try this by starting from a stoplight at easy throttle then once you get moving (don't give it a chance to upshift) floor it and it will drop to first gear and take off hard.

my truck takes off in 1st gear no matter how i take off.....i have counted the shifts many of times.....and every time it shifts 4 times......

I think he's right (atleast on the 03's). Mine will do that. Between the Bama tune, and adjusting my bands, I can definetly feel every shift.

On a side note. That autotap sure looks like fun to play with.

True, but you have an older model with the 4-speed automatic while mine for instance has the 5-speed automatic. The extra gear placed between first and second (or actually 3rd on the newer 55RE trans) is the normal light acceleration gear from a stop. You have to really tromp on it to get it into the actual first gear. Take a newer 5-speed auto in the "D" position and try to ease into a brake stand/power brake situation and it will barely do anything because it is in the second gear. Drop the selector into the "1" positon, and it's on. BTW, I've only tried this once...lol...I prefer not to have to pay for a new trans and I am 30 now so power braking and smoke shows is long since over for me. Like I said, if you easily take off to about 10-15 MPH and then floor the pedal, it will drop down a gear and take off even if it didn't yet upshift from what you think would be first gear. I don't think the torque converter lockup function is even in effect until the OD (5th gear) anyway. Now, with the Bama tuner, the basic function is still the same, but the shifts are much more firm and quick especially at WOT or near WOT situations. With my stock P225 tires on and the 93 octane performace tune in place it will actually chirp the tires (or tire since I still have an open 3:55 rear axle) on the first to second shift at WOT.

ummmmm actually i have the EXACT same tranny you have in your truck..........my truck came from the factory with the 5R55E tranny just like your truck did.....Ford started putting the 5R55E tranny in in '95 with the OBDII computer.........95% of 4.0 4x4's have this tranny in it from '95+...

I can't tell you anything about shifting with an automatic but I can give you some numbers on performance comparison between Bama 91 octane torque and performance programs.

I tried doing 0-60 times but they were too inconsistent due to wheel spin and the variable of shifting. I came up with a test that would eliminate wheel spin and shifting to get consistent results. All the tests were done in third gear with a manual transmission. I also had a 350 lb shell on the rear but it was there for all the tests, so it has no effect on head to head comparison.

I used 40 to 70 mph times trying to represent torque and 50 to 80 mph times trying to represent hp. I used an accurate stop watch to record times and I used only the speedometer for speeds.

40 - 70 with 91 torque program was 9.0 seconds.
40 - 70 with 91 performance program was 9.0 seconds.

50 - 80 with 91 torque program was 8.7 seconds.
50 - 80 with 91 performance program was 9.1 seconds.

I can't explain why the torque program out performed the performance program at the higher rpm but I think the performance program would look better if the test ended near red-line .

If anyone is interested I also have numbers for stock and the 87 performance programs.

40 - 70 with stock program was 9.7 seconds.
40 - 70 with 87 performance program was 9.0 seconds.

50 - 80 with stock program was 9.9 seconds.
50 - 80 with 87 performance program was 9.45 seconds.

I am only reporting the numbers with test as consistent as I could get them. Some of the numbers were averages of several runs and others were just one run.

I got the best gas mileage out of the 91 performance program and the 87 performance and 91 torque programs were similar in gas mileage. They were all better in gas mileage than stock. I used three tankfuls of gas to measure gas mileage of the Bama programs and most of it was city driving.

lifted97ranger....I stand corrected about the years of the transmission availibility. I did some research and now I know that you are right. Sorry about that!

This may be true on your truck. But it's not on mine. Mine always starts off in 1st then shifts to 3rd unless I'm at about 40%-50% throttle.

If I put it in 3rd it stays in 3rd until I bounce off the rev limiter and won't change no matter how much throttle I give it.

Maybe it's an 04+ thing? I have a local friend (04 FX4) who also has autotap on his laptop and he reports the exact same thing.

Thats an awesome post right there! Very informative!
