Replacing the filter won't do a thing. Flush/replace the fluid.

When my 03 Chrysler PT warms up it will no longer go (forward or backward), yet when the car is cold it goes fine .... ???


Hi there, I have seen it once before when the transmission oil was really old, try a service on your transmission first, it's a filter change and new oil, hope this helps

3.4L Cold start problem--slow cranking/firing--below freezing, now it is around 0


May need a bigger battery if cranking speed is too slow. Thinner oil helps some (like mobil 1) might even consider an engine heater,they are pretty cheap and really work great,saves the engine also.The fuel line deicer is a wise move,especially with the new gasoline these days.

Transmission Question


It sounds to me like the transmission is starting to fail. As the clutches inside the transmission wear the clutch pack gains additional clearance. Your pressures in the transmission will be higher with cold oil so it has a tendency to build a bit of extra pressure, but it's also slower in flowing through the transmission. This results in a harder hitting first gear. As the transmission warms up, it will reduce the viscosity of the oil and work fine. Cold weather kills automatic transmissions. Let it warm up before driving it or it won't last long. It will require an overhaul soon.

Car runs for 1or 2 minutes then shuts down


Crank sensor in the engine could be becoming oil logged. works fine when cold. fails when it gets warm. accessable on the back of the engine between the engine and transmission.

What transmission fluid is best in my "standard


Synthetic 80/90 hypoid works great for freezing/cold climate driving. You may notice it is harder to push the transmission into gear. some times the syncros slip more with synthetic oil slowing down the gear speed/mesh action (a slower-harder shift). If you notice this after the oil change, and do not like the synthetic, it is not that expensive to change it back. If you do a lot of driving below 30 degrees or especially below 0 degrees you may want to try synthetic hypoid. it makes driving in cold weather a breeze (no holding in the clutch for five minutes while the motor warms up).

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...


READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....
