    Wow, I searched for weeks, then this video popped up as a "recommendation". Well done, sir.

  • @usuallyfixingtinkering

    Main issues to summarise - Loss of shifting between gears could be Solenoids A & B Malfunctioning, this will throw a code! Replacements are easy to obtain and can be had with a filter service kit.
    Loss of either/both 2nd and 4th - Broken Servo Piston Rod and/or worn Gear Band (usually the piston Rod).
    Very harsh shifting between 1 & 2 - Broken Accumulator Spring/s.
    There is another issue of the stator/pump bushings wearing prematurely causing pressure leakage, this stops the Torque Convertor Clutch from engaging in 3rd and 4th. Very unnoticeable apart from worse fuel enconomy than usual on motorway/long distance driving.

      Very informative video thanks. Would you happen to have an insight when my focus has no computer error whatsoever. No dtc on transmission or solenoid. But my car moves forward when in Neutral. I have no reverse. It launches but stops at Park, maybe parking pawl engages. At Drive it moves forward normally.

      @@kaletsugas thank you sir, how do you mean moves forward in neutral? These gearboxes don't throw many codes it's very rare unless a solenoid has failed. If you have no reverse that's a hydraulic issue, reverse requires way more pressure on the clutches to operate. So if there's any issues with pressure then it would manifest as no reverse first of all. Check the fluid level from hot, drive it take it through all the gears, just hold it in each quadrant. Then check dipstick. What colour is the fluid?

      My Focus Mk1 with this box has an issue where sometimes it does what feels like a hard shift, usually when driving slowly so it's going between 1 and 2, and then will go into limp mode.
      Replaced the valve body along with the solenoids, but still persists. No fault codes on the diagnostic.
      Any ideas what it might be...? Likely to be the box or something else? Speed sensor? Earth connection?

      Hello, dear. My Focus does not shift into fourth gear. Also, the tiptronic does not work. Kicks between 1st and 2nd gear. The oil is almost fresh. The problem began after replacing the fuel pump motor. There, I disconnected the battery terminal several times. And by mistake, I punctured the adsorber tube. And that's it. After which problems with the gearbox began. The mechanics cannot find what the problem is.

    My 4F27E gearbox wants to go forward all the time. In P gear, the car does not move, but the engine does not spin up above 2000 rpm. In N gear, the car goes forward. In D gear, the car starts from 2rd gear and switches normally to 3rd, but when switching to 4th, something strange happens. If I use manual mode 1-2 gears, the car goes perfectly. Please tell me, is the problem in the valves or is the FORWARD clutch pack jammed? Thanks

      @usuallyfixingtinkering  13 วันที่ผ่านมา

      no the forward clutch does not work all the time, I think we have a valve body fault which would be difficult to pinpoint unless it was slit apart like I did here and to inspect everything and every valve, it sounds like a stuck valve allowing inapporpriate pressure to the forward clutch pack at the wrong time!

    Great video, thank you!
    So, in my focus, it's not shifting into third gear. Revs go up really high, clunks, then goes unto limp mode. The error code is p0772 or solenoid E stuck on. I've checked all the solenoids, and they are within spec with their ohms. I've replaced Solenoids A and E simply because I already ordered them.
    Still having the same shifting problem. Same code as well. Any recommendations?
    Cheers!

    • @usuallyfixingtinkering
      @usuallyfixingtinkering  11 วันที่ผ่านมา

      firstly did you buy aftermarket solenoids because they can be 50/50 whether they work well. Solenoid E stuck on - this controls the release of an important servo piston that basically releases the brake band to get 3rd gear. So not getting 3rd gear tallies up with the solenoid being stuck on. My recommendation is removing the valve body, carefully stripping and seeing if there's a blockage going to solenoid E or anything in the passageways! Certain if the solenoid is in spec!

  • @javier.villatoro
    @javier.villatoro 3 หลายเดือนก่อน +1

    I have many problems with this transmission. The first thing is that when the transmission is cold, it gets stuck in 3rd gear limp mode and the OD light flashes without a code. If I shut off and turn on the vehicle a couple of times, it engages 1st gear. The other problem is when shifting to 3rd gear, it engages for a second and then slams back into 2nd gear. 4th gear directly slips. The only code present is P0733. Do you have any idea what the cause of these problems could be?

    Mine is at 130k. 2011 4spd SEL model. As soon as you put into drive. Wrench light comes on. I pulled codes and i cant remember exact code, but it was for a shift solenoid c electrical circuit malfunction. I replaced the shift solenoid c. It does good on all shifts EXCEPT into 4th. It will go into 4th and immediately slam back down into 3rd. Any advice? Do you think this is electrical?

      Of course sorry I didn'nt think, it's difficult to diagnose that issue but it may be the servo piston in the sump area is worn and bleeding pressure between 3 and 4th, its a round rubber disc covered by a small panel with three nuts holding it down and it had a shaft that pushes on one of the clutches, this does wear or even breaks, if that happened though it would affec 2-3 shift, so may be just worn. If it is it is a tricky repair and needs reboring by a transmission specialist to refit the old piston.

      @usuallyfixingtinkering that's what I was curious about. 2-3 isn't bad is why I'm stumped. And no slipping between 3 and 4. It goes into 4th but shortly after quickly jolts down. Weird weird stuff.

    Thank you sir.I have question. I have bought new automatic transmission and mounted.
    The vehicle is running smoothly for the first time, I do not have any problems with gear shifting. However, after driving an average of 15 km, the light comes on and turns off after 1-3 seconds. After 1-5 seconds, it turns on again and goes off. Finally, on the 3rd time, it turns on and does not go off. After the light stays on, it turns off.
    The vehicle does not feel any problem at 1-2 revs, but it becomes a slight problem at 3rd and beyond. That is, when shifting to 3rd, it holds it and releases it, that is, the shift is felt, when the revs are completed, it is felt at 3.7 revs, not 3.2 revs. Afterwards, it should complete the revs and shift to 4th.
    It passes at almost 5 thousand cycles, sometimes it doesn't.
    In this situation, when you pull the car aside and turn the ignition off and on, the light goes out and returns to the beginning, so it does not cause any problems until you drive 10-15 km. Afterwards, the same problem occurs.
    Sometimes, while driving with the light on (transmission protection light off), the gear shifts to 4th and continues, but when the light comes on, it shifts to 3rd.
    The oil has been changed and the transmission has been reset. The old transmission and the new transmission give the same malfunction response as if it had never been changed.I m getting same problem new and old transmission.
    OBD says P0741 fault
    Im sorry for long write...

      That code is the Torque Convertor Clutch Solenoid which allows the lock-up in high gear and higher speeds - I've never heard of one failing in that box to date so first thing is to check that the transmission fluid level when HOT and gone through all the selections for 10 seconds with the engine running... see what it says.

      Firstly check that the fluid is at the correct level, get the car hot, check the dipstick! Reverse is always the first gear to be lost when there is a pressure issue, far less pressure is needed in Drive. Check the fluid.

But now it does it almost immediately and I can’t “soft reset” it with the key. Ecu failure?

      As traditional slush-box automatics go they are very reliable if they are not abused and treated like it can produce the peformance of a manual. As long as the fluid is check and changed if it has not already been done so there's very little to go wrong. The main weakness are Shift Solenoids A & B, which will reguarly be supplied with a filter and gasket kit when changing the fluid. They CAN pack-up but its not a hard job in the slightest. Compared to the Powershift gearbox which replaced this around 2008 or just after, this is 10x more reliable.

The trick of telling- the Sump pan should have no gasket, if you can see one the fluid has been changed previously, as a gasket comes with a filter kit. Originally it was just stick on with sealer which you may see if its untouched.
