hate to ask another E4OD question, BUT...
Hope you don't hate me asking questions first thing:
I'm having trouble with a '00 e350 econoline with a 429 v10. It all started when I had some really bad trouble with the idle all of a sudden. The crankcase ventilation line (right below the TB) dry-rotted and collapsed, causing the IAC to act sporadically.
The lurching was so bad it would almost chirp in 1st. Needless to say, we got it home right quick. That's fixed now, the engine runs like a top: but when I took it out for a test run, it had a hint of a slip in first, wide open into 2nd (with a big slam) barely make it to 3rd when it's cold (out of the question when it's hot). If it does catch 3rd, it barely holds it on level ground. 1st and 2nd do just fine manually.
I've read almost every related thread on here but I can't find how to test the solenoid pack and/or:
correct the occasional P0228 I get when the throttle snapped open.
That's another thing; could these symptoms be due in part to the TPS high input Vs?
Nothing is wrong with anything else in the engine or powertrain.
Also, what is the database for the TFT? I mean, would it/should it make a quiet buzzing sound like a fluorescent lamp?
Thanks so much in advance

The first rule of fixing a transmission is fix everything on the engine first. ANY engine problem will cause the transmission to run poorly. Fix the P0228 and any TPS problem before doing ANYTHING to the transmission. A high reading on the TPS can cause the problems you are seeing.
I have no idea what you are asking about the TFT (Transmission Fluid Temperature) database. I'll take a stab at it. There is a table in the PCM that takes the voltage from the TFT and converts that to a temperature. The PCM uses this temperature as part of the strategy to control the transmission and torque converter.
There is nothing in the transmission that should be buzzing.
(BTW, I've seen them both called the same thing.)What I was talking about on the TFT is weather it is frequency, voltage, digital etc. based so allowing for noise in that area,(KOEO), but I guess I have my answer to that already.
So, how would I fix a high input voltage to the position sensor?
P.S. the tps is brand spankin' new.
