Tranny comparisons

Alright, so i've had an '02 f250 for about 6 years now and an '01 f250 for about 3 and they both shift pretty much the same. 02 shifts a tad different depending which setting the ts6 is on. But overall feels about the same. I bought a L99 f350 a couple weeks ago to replace the 01, (work trucks). I can definitely tell the gearing in the diff is different but the transmission in the late 99 shifts way different than the other two trucks. I was just wondering if someone could shed some light on this for me. I was told the 99 is all stock. looks to be so motor wise.

Thanks in advance.

Ps 01 is all stock to.

It's simply the way and when the transmission is commanded to shift based on the calibration in the powertrain control module.

Does the 99 have the same transmission as the other two? or is it just the pcm is programmed different in the 99's?

It's the programming. The transmissions are identical.

ok thanks for the great info. One more question, riffraff has the ts 6 position on sale and i really like it in my '02. I'm guessing if i install that it will shift like the '02???
also do you guys like the gearing on the 1 tons? I'm running 2400rpms at 74 Mph. Im pretty sure it has stock size tires.

No, It will shift like a 99 with tweaks....A tuner doesn't change your Base PCM program, They rearrange some of the performance parameters.

Wrong.

It depends on the current calibration in the PCM.

If you get a TS Performance brand chip, then it will shift pretty much exactly like it does now. However if the one you buy from KT performance is the power-hungry Phoenix athen yes it will shift like your 02. TS performance does not use the same calibration as other tuning companies.
