Question about Cars & Trucks
I have replaced raditor,new larger oil cooler injectors done but still over heats when worked hard,if i turn on the heating fan and open the bonnett it runs much cooler
Coolant temperature sensor could be faulty because cooling fans should turn on at 190 degrees and make sure cooling system has the right amount of coolant in the cooling system.

Hi, these are two separate issue here.
The abnormal shift is isolated within three ares. i would suggest checking the transmission fluid level first to make sure of the proper level. if its low, you will experience Miss shifts of this nature. if the fluid level is sufficient, i recommend moving your inspection to the TCM(transmission control module). this is the control module that initiates the correct shifting intervals and it relays the actual shift signal to the shift solenoids located inside the transmission pan. if the module is malfunctioning, it will affect the shift patterns dramatically. If the module is in good condition, i would then move on to the actual shift solenoids themselves.
These devices preform the engaging of the gears within the transmission as stated above. if this device is not working or is malfunctioning, it will affect the way the transmission shifts. If you have not preformed a proper transmission flush and have not changed the filter for a while, it would help if this maintenance was initiated soon if possible.
Now, concerning the overheating issue. if the fans are running in a correct manner, this will most likely point to a faulty water pump or an faulty thermostat that may be froze(stuck in position not allowing proper water flow). the most common fix will be to preform a radiator flush. during this flush, if you notice a rusty water flow and tiny metal fragments running out the radiator, this will confirm extreme radiator damage to the inner coils and it will have to be replaced or rebuilt. I would recommend flushing the radiator and testing both the water pump and thermostat for there operational value.
Please rate and god bless:)

SOURCE: No heat. Fan blows cold air.
I think u may have an air temperature control blend door problem, the door is moved by a small electric motor, it is stuck in the cold position.

SOURCE: 1996 audi a4, no heat.
Sounds like your thermostat is sticking open, when this happens your coolant in your engine isn't given enough time to warm up and just cycles threw to your radiator, which cools the fluid not allowing it to get warm/hot. Thermostat tend to go bad, this is most likely your issue, just have your thermostat and gasket for your thermostat replaced too. Your looking at about 10 dollars in parts maybe 20 dollars in labor! If this helped give me a thumbs up please!
