This is what happened with the Autozone filter. The OEM filter solved it.

I believe it was 2200 ohms, and it went on the pressure sensor wiring from
the sensor output to the
ground wire (I think -I don't have the Transgo instructions handy). I
checked this
about 50 times after the truck stopped moving...

I decided this was BS myself shortly after smoke came out of the filler
tube....

I think both "Huh?" and "No" are appropriate answers here..Where would I get
this done?
Dealer?
The tranny I'm looking at is out of a 2004 Ram 2wd V8. That would be a 4.7
or 5.7, right?
The price is excellent, and I wouldn't mind getting it for a spare if it
would fit correctly..

Subject: DML: 2K 4.7L/RFE45 troubles
I have recently started having tranny troubles since the weather has turned
cold here. First, let me tell you the mods done to the truck:
It has the Transgo reprogramming kit installed, with the resistor mod. It
has 2005 HO cams and intake, Airaid filter, Fastman TB, Gibson cat-back
exhaust, and Jet stage 2 chip.
I had a little trouble with the Tranny mod I did in the spring; the Transgo
kit was good but the Autozone filter I installed did not seal at the pickup
tube. I got about 1/4 mile from home and the truck would not move anymore,
and I got codes related to tranny pressure. A call to Transgo suggested
there was dirt in a valve, and to rev the crap out of it in gear to try to
blow the dirt out. I quit that when smoke came out the filler tube, removed
the pan again, saw that the pickup tube had fallen out of the tranny,
replaced it with a Mopar filter, and all was mostly well. It would go into
reverse immediately, but would take a while to drop into drive. After about
a week and another quart of -4 fluid, it worked well until this week.
On the first 25 degree day, I got a tranny pressure code (sorry, can't
remember exactly what it was, but it was the same one I got before) as soon
as I started it. When I got to the first stop light, if floated back and
forth between drive and neutral until the light changed. I revved it a
little, it dropped back into drive and I went to work. When I got home that
night, I reset the code and it didn't come back. The next cold morning it
did the same thing at the first stop light I hit - then at the second one it
seemed as if the torque converter stayed locked - It killed the engine when
I stopped. Started it back up and it worked fine going to work. Same thing
happened coming home - didn't want to stay engaged at the first and second
stop, and killed the engine at the third stop. Then worked fine the rest of
the way home. I checked fluid when it was hot - it was between the 'full
cold' and full hot' marks, so I added some tranny fluid. Next morning, same
thing, except it killed the engine twice. I noticed on the interstate it
didn't really want to slow down when I let off the gas. When I hit the next
stop light, it was hard to stop and it was idling at 1500 rpm in gear - 3000
rpm in neutral. Hit the throttle a couple of times and it wouldn't come
down. Dropped it back into drive, chirped the tires and drove the remaining
1/4 mile to work. Parked it and put it neutral - 3000 rpm. Without touching
the accelerator, I shut it off and restarted it. Idled at 600 rpm, just as
it should. During the day it warmed up to 50, and it worked fine all the way
home.
A couple of questions: First, does anyone have a clue as to what is going
on? Second, there is an RFE 545 tranny out of a 2005 for sale locally - is
that a drop it replacement for my tranny?
Thanks,
Ned
