Not sure how to start this but here goes. I Finally bought a DP-Tuner and got is saturday. Got it on with no problems and WOW this thing is unreal! ok that was the fun part. Yesterday a buddy calls me and says he broke down in Attica, IN @ the badalands.(He's drivin a Jeep). So I get him we go rent a Uhaul car hauler and load up his Jeep and I take him back home to Cincinatti where he lives. Everything is goin great no complaints. On the way there I used the stock setting cause I didn't get the tow settings on the DP-Tuner.( Could kick myself in the @$$ for not gettig a tow setting.) Then on the way back I'm pulling the trailer, empty, and decide that I'm gonna put it on the 80e setting so I can get better mileage. I didnt think that it would hurt anything since the trailer was empty and not putting the truck under a load. I get back to the north side of indy and off the interstate on my way to drop off the trailer and my overdrive light starts blinking but the truck is driving normal. Then I get to Uhaul and unhook the trailer and I get in my truck to take off and it doesnt want to shift into 3rd gear. Now I'm freakin out. I take it nice and slow on the way home with a top speed of about 35mph. I get home check the fluid and its at the top of the hot reading but its brownish color and it smells burnt.
Today (Tuesday) I get up and take it to A guy I know fairly well. He hooks up his computer and reads the codes for me and this is what I get.
p0732
p0733
p0603
p1211
p0782
p0781
I've never had any codes thrown as far as I know until now.
I need help on trying to figure out whats goin on and what these codes mean. and where do I go to look up these codes? A huge thanks in advance to those who have any input.
I can only provide a little help. I have a 4r100 service manual, and the codes define below:
P0732 2-3 shift error because of SSA (shift solenoid A), SSB, or internal transmission components.
P0733 3-4 shift error because of same reasons above.
P0782 Defines same as P0732, but, I would make an assumption that the code applies to a different function. Example 0732 may be SSA, 0782 may be SSB, or, vice versa.
P0781 1-2 shift error because of SSA, SSB or internal transmission components.
I have no clue what P0603, nor P1211 error codes are. The scope of my manual is somewhat limited. I would suggest calling the local dealer and bounce them off of their service department. In the mean time set your tuner to stock and change the transmission fluid, and see of that helps. Perhaps one of our more knowledgeable transmission members could help.
Well I'm gonna start with flushing the fluid and see where that leaves me. I've got the overboost anhilatior on order from ITP and I'll check my oil level but I'm pretty sure I changed it towards the end of february. I'll proll change it anyways. Thanks for the help I'll let you know what I come up with after I do the tranny flush.
Ok so yesterday evening I did a transmission flush using the instructions that Neal posted on here( thanks Neal) and the fluid was definately burnt smelling and was a dark brown. There were'nt any chunks of metal in the pan when I took it off which is good. I did change the filter put everything back together and then continued the flush. After completeing that I added 2 bottles of the Lucas Oil tranny fix stuff. Then went out drove it and it seemed to be better but it's still not shifting normal. I'll be driving it more today while at work so we'll see how it goes. Thanks for the info and the help. We'll see what happens.
I see you have an 01 could it be the mechanical diode
I thought of that, too, but the failure mode for a mechanical diode is no 1-2 shift. Once you get it fast enough it usually will shift to 3rd and then 4th. So it's possible, but not likely.

that was my thought,but thought I would throw it out there hoping you would drop by
When I was researching about the shift solenoids in these trucks I came across something about certain solenoids in the 2000-2001 trucks being prone to failure. If I was you I would probly be changing that.
There not to bad to change, you have to pull the pan though.

What's this mechanical diode thing all about? Is it easy and cheap enough to change just so I could eliminate that as being a problem?

I'm assuming that these solenoids are a ford only part? I wonder if there is anyway of bench testing these so I would know if they are bad. @ $200-$300 a piece it's kinda pricey for just a trial and error method.
Taking off from a stop it did'nt want to shift into 2nd without me getting on it a bit and then letting off.
Everytime it upshifted into 3 and 4 it was harsh.
Sometimes it would also seem to just skip 2nd and go straight to 3rd or 4th. (This kinda sounds like this Mechanical diode issue)
Maybe the transmission is shot but I can't afford a new tranny at the moment. Usually it's not the case but maybe luck will be on myside and I can find somthing other than a rebuild that will the transmission.
Also yesterday when the overdrive "off" light would flash it would somewhat slam into drive from park. Then I would put it in park and shut off the truck. Then start it up again and the Overdrive light would not flash and would shift into park normally.
