AL4 DPO Automatic Transmission Service Fluid Refill & Level Check Renault Citroen Peugot How To DIY 

I've put a bit too much in there - classic! Great instructional video, thanks.

As soon as I heard the symptoms.. I thought blocked filter.. had a trans eat the lockup clutch lining and symptoms matched, pulled the pan and the filter was a mess of what looked like fine mud.. thanks for the upload your becoming a regular reference point for diagnosis of trans faults. Awesome job buddy!

Top job boys.

Thanks for the video, will come in handy. Have to say tho - the idiocy of the engineer not putting a dipstick on such a vital part is just beyond me..

Thanks that helps

Hi, great mechanic, lean and effective! I love the idea of using the leveling bolt to refill it back with no need of dissasembling parts somewhere else. Q1: what is the diameter of the hose that fits in the leveling bolt-pipe? Q2: what do you use to pump the new oil in? Any links to products are welcome. Thank you again

Nice video you spoke about putting an external filter Can you tell me or do you have a video on that.

sir this same gearbox renault duster 2.l petrol 4 speed amt geabox , id yes we can fix this gearbox to renault

رائع 👍❤

Hi, great vid, did the oil change fix the customers issue. I have the same transmission and I am having the same symptoms.

Same box at Renault on Megane 2, called "DP0" ("AL4" at Peugeot and Citroën). They say 60°C to check the level.

Hi. When draining an automatic gearbox you only get about half of the oil out. The other half is still in the torque converter. If you just refill like you did you end up with 50/50 oil. 50% new mixed with 50% old. That's why when you removed the level plug to set the oil level the oil that came out was nearly as black as the original oil. When I did mine I used 20 litres of oil. Drained as much as I could. Refilled and set the level. Drove for a few days and repeated until all the 20 litres was used. Each time you drain you remove more of the old oil. 1 drain and refill = 50/50 oil. New/Old. 2 drains = 75/25. 3 drains = 87.5/12.5. 4 drains = 93.75/6.25. Obviously these are very loose figures. Yes, it is more expensive but you end up with a better job. Unfortunately on the Megane Scenic the oil cooler is built onto the gearbox and is cooled by the engine coolant via an oil to water heat exchanger. I cannot see how an inline oil filter could be used if there are no pipes going to an oil coiler radiator at the front of the car. Also, on my car the oil change didn't fix the jerky 1st to 2nd gear changes even after stripping, cleaning and rebuilding the hydraulic block with new solenoids at the top. Couldn't change the gear change solenoids as I couldn't afford them at the time. This is an UK car.

Hi. How long does it take for the old oil stuck in the torque (about 2.5l) to get fully mixed with the new oil. Does it mix quickly by pressure/hydrolics with a 5 minute drive, or is it much slower and maybe takes a few weeks/months of driving? (I left mine draining overnight to see if the torque would empty on its own through the seals but I hardly got any, maybe a tenth of a litre, and probably not even from the torque)

All of the manuals I found says 60 degrees (C) for checking oil level

Inline filter will do nothing other than filter coolant. Common issue with AL4. Can also check pressure regulation valves pressures on the valve body via scan tool. Seems AL4 has an issue with dealing with hot ATF. Users in Brazil have had good results with Dextron6 fully synthetic.

Hola que puede ser que el auto a penas lo pones en marcha la marcha a tras entra sin ruido y golpe. Pero en caliente si hace un golpe leve cuando pones marcha a tras. Tambie lo hace en 2da cuando está en frío y salís cambia de primera a 2da rápido a bajas vueltas. Pero en caliente al cambiar a 2500rpm y pega un pequeño golpe. Los demás cambios funcionan sin golpes.

Hi. I'm from Malaysia. I own the Peugeot 207. AL4 gearbox 4 speed. I also got issue lately same as the car in the video. Slipping shifting during hot time. On the afternoon driving especially. I'm nearly want to make fully restore on the gearbox. But then I've using the Mobil 3309 atf. The gearbox issues gone and the gear shifting become smoother.

I have a Citroen c4 coupe (2007) with automatic transmission, I would like to do a complete flush instead of normal change, but this requires opening the transmission coolant lines in order to empty the oil from the torque converter, do you know if this technique is possible with AL4 ? Where are these coolant lines located in the Citroen c4 ? Many Thanks in advance

Its only change or also flush the oil?how to flush the al4 matic oil?

Hello I have a Peugeot 207cc al4 automatic transmission how much liters to make a drain and refill ? ( A normal one without the torque converter)

i have 406 coupe 3.0 liter with this transmition automatic and gearbox not changing second gear and suddenly car stops all wheels blocked what can be the problem i change the oil 10k kilometer ago please help

hi, if the oil mix with coolant what should do?

I have a 2006 Citroen C5 model 2.0 16v (AL4) automatic transmission vehicle. I get transmission failure when it rains. I am getting error U1003-0103 in OBD data In addition, the vehicle changes gears on its own while driving on the road. When the rain stops, my car returns to normal. Errors cleared I think part of my car is getting water and the problem persists until this water dries up. What is the faulty part? Help me! please

Can you tell me how to flush the atf al4?

your help is needed please can you help me .

Great video. One question though...what's the website address for the gearbox oil?

Hi ... how can you fit an inline filter ?

2009 mercedes V6 takes the cake for the most stupid way to check the trans level,all done through a digital display on the dash,it tells you it needs more fluid,but not how much, so err on the side of caution when refilling,the stink part is you have wait 15 min between rechecks whilst the computer does it thing for level checking.Took me an hour,whilst a dipstick takes 10 seconds.No wonder they lost the war. Just changing the oil on the peugeot wouldnt have cleared the block filter,,maybe some compressed air through the cooler lines might have unblocked it then another oil change ?How did it go after your service ?

You should ONLY USE lt71141 fluid and nothing else in the al4 box and looking at the colour of that fluid ud say its been in a bit too long, and it could do with 3 more sucessive changes to get all the old stuff out for max life

is this transmition repariable rebuilding cost expensive and where

Does this gearbox has filter ?

is this a problematic automatic geatbox system...??im asking cuz i wanna to buy a renault megane coupe 2001 model ...

What's liters???

Actually it's only use 2.5~3 litres of ATF oil. 😊

AL4 service
