Look I gonna be open with you guys , it's 12:00 pm right now , gonna go reading thru all the treads I can ..and start working on this tomorrow at dawn ,I'm this close to throw a grenade at my tranny! ,this what happen : coming out of a parking lot , try to put the gear into reverse, a little faster than usual, mind you ! ..when all of the sudden nothing happened ! ..only the usual VROOOMM ! VROOMM! ....so ..the only thing did notice was a slipperin/something is grindin,very ,very softly kinda noise among the rest of the noises in the truck
(have a very good ear )(kinda of ironic since I was reading about the shifting problems on ford trucks on fte,which I had on mine)..so..to make a long story short .. manage to drove home(all other gears , worked fine ) ..took a long hard look below the truck..and nothing is wrong ! ..fordboy talks about a solution for transmission valves but only 4r55e and 5r55e..mine is 4r44e !!!!..does it apply to my number ???,I'm asking since if I'm gonna try to attack/fix this REVERSE problem,right away , mind as well do the fordboy fix as well ..I'm soooo mad at MR .ford right now! , thinking of mixing some gas with orange juice to make homebrew napalm !.. (or was it sulphuric acid??..lol !)to burn the %&*** out ! ..anyways I need to shoot something ..so I'm gonna play halo 3 with the kids (uumm! they taught me ! Honest, not that I'm a fan
or anything !..)..anyways any coments are welcome ! thanks in advance !

hey ! rockledge ! yo ' cool man ! seen it !, read it ! ..will do ! ...inspecting !
..inspecting..will keep you posted as to my progress ! ok ! thanks !

 

Decided to take the tranny to the shop ..being a newbie at this , the outscope was too much for my limited tools and time , got desperate!..anyways here's the story : took the shop about a week to fix the problem, (they had like 2 or more trucks ahead of mine )then when I got there , the guy was testing the truck, rode in , got off, and told me , that there that they had fixed the reverse problem,did solve the reverse problem he said... but ..now it have a PCM problem !!!.. still no reverse !!!!..seems ..the guy told me that the PCM was still recognizing the reverse fault , 'very common problem the guy told me' and that they needed to repro ' the PCM (sucking all the info from the PCM ,clearing the faulty code , then reinserting the info again, and problem fix, which got me nervous! to say the least!) ..anyways to make a long story short..they did change the broken band ,and supposedly did a medium overhaul, that is o-rings, gaskets, the discs 'pads' were a little worn (ok ,not to replace) etc.. etc..seems that if you take out the transmission (blue cover) ´connector ´to the left of the DTR sensor , (I only see two connectors on that side ), the reverse works fine !, but the motor goes rough , can take only till 3rd gear , he told me ,also the OD light flashes on and off ,(they cleaned the PCM connector and all tranny connectors to no avail ) if you plug 'that' connector again , I am back at square one , all gears ,all fine , no reverse.
took it home , ..yep ..,hard to drive, have to help changing the gears manually to help the transmission shift ,when it doesn't want to, ..
1.-is there a way of reseting the 'computer' (diy) assuming is true?
2.-could it be the DTR sensor misaligntment? or any other electrical things for that matter?
pleeease ! heelp ! any comments are deeply appreciated guys,!

 

like I said thanks in advance !

 

I had the same exact problem, I took mine to the shop and they told be it had shredded a band in it!

 

I have to say after all that I would drive my truck through that guys shop if he didnt fix it!

 

joshc_guitar ! thanks for your reply ! ..look I took that decision base on the fact that the shop didn't have the apparatus to repro the PCM , besides it had an extra prize tag ,
(they outsource for that kinda problem) ..like I said the truck does have mechanical reverse ,confident they did resolve the reverse mechanical problem.

 

aside from josch_guitar ,err..anyone else ..anyone ?

 

Well that makes sense then.

 

Is the summary that they replaced the broken band, some other seals and internal parts, and it doesn't work right? I hope you paid with a credit card so you can dispute the charge. If they took your money, then they should have taken the truck to a garage that *DID* have a 'PCM' dealie, and get it fixed.
I find it hard to believe that the PCM remembers a broken band. More likely, they messed a sensor up, or did not put it back together correctly.
Thinking of those pieces that you step in that fall out of bulls....

yep, been thinking along those trains of thought lately ...seems I need to examine the tranny again , which I 'm doing right now , on the lines of eliminating step by step ,probable causes ,symptoms, and even sensors, ..even theories I find on manuals and friendly advice just like yours , thank you !..will keep you posted as to my finds..

NO!!! You need to take it back to the shop that took your money and tell them that it still is broken. Why are you doing anything trying to diagnose a problem that the shop put into your transmission? THEY did the job. THEY took the money. THEY robbed you. If you are OK with that, then fine.

I really now that tomw! ..but ..I'm not in the USA ( take a look at my profile ) ..I'm in latin america right know, believe me ..kinda different set of rules down here , if you take my drift , that's why I decided to take my loss , and walk away and try to solve the problem either by myself or on a different shop , let me explain ,many bussiness transactions over here take place as in handshake kinda deal ''no paper'' or ''signatures''
although angry as I am , have to play by this country rules which is ´no rules at all´ if you know what I mean , I will explain this further in another post , btw thanks for your
reply and motivation I know is all in good faith , god bless !

 

Update : After going thru some diagrams and FTE forums decided to clean/inspect the infamous ' monster' connector of the wiring, below the drivers seat , after that I reassemble it back , and guess what ! .. (with the blue connector that's on the side of DTR sensor plug in the tranny) , the tranny gave REVERSE !.. tested one more time at the garage ..and it give it again !.I was elated !..altough did sense a very loud thump, and also with brake pedal pushed to the floor , you did feel the truck 'momento'..thought of doing a little test drive around the block , just for testing pusposes , run it then stopped 6 times (full stop) ,put it in reverse , and the 6 times it worked ! ..then decided to run it forward a little .. slip betwen 2and 3rd , I'll guess , and after that went reverse dead again on me , ..posting this in case someone has any toughts , now have CEL light on all the time ? could it be a electrical problem ? cause how come it worked for as far as 6 to 7 times normally ?
