307 overheating and automatic transmission problem - 307

Hello friends
I just bought the 2004 model 307 1.6 pack SW automatic gear car. My vehicle is at 138 thousand km. I had been traveling with a heater for 3 days, there was no problem. Today I closed the heating system because the weather is nice. traffic was congested, we did stop and go, the temperature indicator came up to 2 lines of 90. The fan worked 90a landed but rose again. After that, when the vehicle stopped in traffic it started to slide as if I was in gear, I stepped on the throttle and went on knocking as if someone was hitting the back. The gears are smooth, no problem after getting up.
Now I thought of something like the result of my research.

1- In the direction of my heat research, it is actually normal. not hot
2- But this normal temperature prevents the oil from performing the required task as it heats the transmission oil too much.
3- My oil is probably old, can I solve this knock problem just by changing my transmission oil?
4- By the way, while I was buying the vehicle, I had an expertise at the bostancı auto report expertise service. The car is leaking oil from the gearbox seal on the left, he said. Even so, I bought the car. I wonder if this leak could have reduced oil to leak? Could the problem be due to this?
5-bostancı in the auto industry, there is a person who is a day auto avni master, is there anybody left satisfied? You önerirmis?
6-Finally, can we adjust the temperature of the vehicle not to exceed 90? Is there such a thermostat?

there are up to 100 ways of heat, so is my 206; he also makes the knock you mentioned about me in very tight traffic; Other than that, the transitions are as smooth as you said. maybe it may be characteristic .. it started slipping like i was wasting the gear in vain what i mean i couldn't figure it out; If you take the foot from the brake when you take it to D already, the vehicle will move slowly; then as you gas it starts to shift.

let me give you a hint; It will not be in congested traffic, but in normal departures, hit the gas hard in the first place and switch to the second gear quickly; both knock decreases; you also save fuel.

Thanks for the answer.

Today, I changed the transmission oil. Bostanci Sanayi Avni Usta. According to what the master said, he continued after 2 or 3 days and then improved.

I found out why the car did the striking. The reason is because I closed the heating system. When the heating is turned off, the temperature increases and it gives the car the feeling of hitting the car from behind. I think the heater is open 2. The fan is activated and cooling the transmission oil. I never encountered this problem when the heater was on.
Why doesn't the fan work?
