[QUOTE = qw12] There is not always knock from 1 to 2, only when he moves from 1 to 2, he is unstable and takes his turn to the gear shift, and then when he passes the gas, he sometimes hits. it is only at low speed in the city. I don't know if this is a problem.
my car 2006 307sw automatic. Before the last hike between Istanbul and Ankara, he burned 100 TL gasoline. After installing teleflex lpg in ankara city, it goes 260km with 35lt lpg.

what would you recommend in this case?

These problems occur across the automatic transmissions. There is an automatic transmission, it stays at the top of the block.

I have the same knock in me when the car goes from 1 to 2 while knocking. I do not care much for now, but I have a mind in my mind the valves that the friend mentioned, namely the valve change.

change the oil first, if the problem persists, there are solenoid valves, you can solve them by changing them. The problem is already due to the heating of the transmission oil and the reduction of the required pressure in the gearshifts, that is, when the temperature is over 90. They say there are more in LPG vehicles because they use the cooling system in LPG and this cooling system is not enough for the gearbox, I am researching how to solve this problem. They say it can be solved with a larger radiator, but before that, I have other problems and I will deal with them and focus on this.

Not even in 40 thousand it is normal I used 0 peugeot on the slopes, it is very rare to hit when throwing from 2 to 1 in low speed sudden stop * It is very rare * If you drive without tiring, what I say is valid

thank you very much for the answers and your attention. I wish everyone an accident-free ride and a happy year.

there is a need for prevention because they can be a problem because they are mechanical things, even engine or transmission makes zero zero
To explain by example; my two friends are buying zero golf from izmir and going to izmir Aydın highway to try the same day, one of them is going well but the other's transmission is locked. So what happened? (of course, the gearbox is replaced and guaranteed.)
To summarize, these are the structure of the servant, everything is expected, some of them cause problems on the day you bought some of them.

Of course, the servant structure may deteriorate, but if this malfunction is constantly happening to everyone, is the problem not chronic? The whole world has agreed that the AL4 transmission is a complete nuisance. The maximum 90 thousand gearbox needs to undergo heavy maintenance. the pressure-losing gearbox is installed in gearshifts. everyone's attention, automatic transmission does not require maintenance, they are very sensitive. Peugeot buyers prefer the new generation AUTO6R gearbox. (Started producing after 308 and 2009 model.)

[/ QUOTE] of course I agree that you should be treated with oil, but they do not have to complain if you have knocked on, they say they should do it and look at them. hareret 90 is past only when it is cold room 3 4 minutes later when it gets hot no problem i don't like to talk big but i bought peugeot used i measured i weighing automatic

In general, I was saying that the automatic ones are not useful, but I went for my wife or not. They did the automatic, but they could not calculate a small detail, that is, the event of losing the feature of the oil when it warms up and the pressure of the oil that loses its feature will decrease in the passes. sometimes I wish I had bought something before when the warming problem is solved. Especially when getting up in the lights, until the folks plug it in to 2, mine has already taken 3 ways (: Heart 307 XT BVA. lives as soon as they are told ...

The transmission has a cooling system, of course, but unlike that water cooling, it must be oil cooled. It uses a part of the water radiator and takes the hot oil back by cooling it there, thus cooling takes place. This cooling process cannot be completed when the vehicle has LPG or excessive force. In the case of hitting in the morning, I guess the pressure spraying cannot happen because the oil is a little dark and not fluid when it is cold. As a result, it is said that this problem is solved in makyj vaults with a larger radiator. I will share the developments with you here.

Dear forum members;
First of all, I am not a Peugot user, I have a 2001 model Clio 2 HB RXT Automatic vehicle. However, when I was researching the subject of automatic transmission, I saw this topic and wanted to contribute. DPO / AL4 type transmissions are generally used in French group vehicles such as Peugot, Citroen, Renault, and are common in problems encountered in general. The main problem with most of these transmissions is that I understand failures in heat transfer and cooling. Especially in the hot summer months, in congested traffic, on the ramp stop / get up, this problem manifests itself more. Doesn't it have anything to do with whether the air conditioner is turned on or not? Now, while doing research on this subject, I could not get enough information from Turkish sites. I searched in a foreign language and got various results. These DPO / AL4 transmissions are known for their warming problems, so these transmissions have been developed in various modified kits. Take a look at the link below:
This brochure has been published by a British company called JPAT (JP Automatic Transmissions LTD). Two products are introduced in this brochure. Oil exchanger for the 1st DPO / AL4 transmissions (heat exchanger) I have translated the text into Turkish:
DPO / AL4 Heat Transfer
DPO / AL4 gearboxes have been on the market for several years, but we continue to experience frustrating oil pressure problems caused by the heating of this unit. Keeping the temperature of the transmission fluid (oil) within the recommended limits is very important for this transmission.
JPAT now offers a helpful kit to help you deal with your heat related problems. The kit includes a new heat exchanger, 40mm deeper than before, and conveniently manufactured to replace the old heat exchanger. In addition, longer fixing bolts and washers are provided so that you can fix the larger heat exchanger in this kit.
DPO / AL4 Modified Deflector Plate Kit
In conjunction with the modified cooling kit above, JPAT now offers you a kit that increases the oil capacity and improves distribution of oil.
This kit includes a deeper crankcase cover, crankcase gasket, a deflector plate (baffle plate) that can be fixed to the valve body with existing bolts, a new level plug with the washer, and a longer level tube to ensure that the increased oil level is correct. This kit is a must have for the revised DPO / AL4 chassis.
If you have English, you can write "DPO / AL4 modification kits" to Google and find other products. As a result, various sub-industry products have been developed that can assist in troubleshooting problems with these transmissions. Does anyone get information from this automatic transmission service with this subject? Does this product is available in Turkey? Thank you.

hello friends 2004 model 307 automatic transmission 1.6 car goes to temperature does not go down below 90 degrees. I went to everyone says that the transmission will drop down to 3500 4000 TL, but it does not make sense to start the problem with downloading the transmission directly.
