Slight hesitation / judder on acceleration
 

Hi guys,

The X is a 4.4i, 2003. I've started to get a slight hesitation when the revs are low and I accelerate slightly, when I really put my foot down the hesitation isn't there but if I just touch the throttle it happens. Any ideas?

torque converter slipping. mine has done this forever. putting it into sport mode will stop the slip.

adding dr tranny instant judder fix will also calm it for a while

I also have an oil leak at the bell housing, this couldn't be related could it? Ie could the oil be coming from the gearbox?

A trans level check may be in order

Is this something I can do?

put car on 4 ramps. Loosen fill plug. start car, then remove fill plug. if you get seepage, then level is fine.

if dry, consider adding some transmission fluid.

HOWEVER, I would be hesitant to say you have a leak unless you see visible signs under the car. Could have a rear main seal leak of oil, not transmission fluid.

Might be worth a trip to mechanic to be certain

My car's been doing this for a while now. It only happens in certain RPM ranges and in certain gears (usually ~2200-2450 RPMs and 2nd/3rd gears). I've checked the transmission fluid level a couple times and it's good. I've read other places that it's possibly caused by the torque converter but i'm not sure how to test/confirm that. I know my TC fluid has never been changed so maybe that would help? I forget if sport mode eliminates the problem or if I just shift differently than the car does so I don't see the problem. I'd love to make it stop as it's rather annoying, but it doesn't seem to really DO anything...

yea, low fluid levels cause either harsh shifts or slipping. this is a torque converter
problem without question
