Morning all,
I have a '02 GTP that has 118k miles on it. Recently I've been hearing a loud (thud) and it seems to hitch a bit when I give it full throttle when I'm going 45-55 mph. It's happening when it's down shifting. At lower speeds if I give it full throttle it seems to be fine. I have checked the transmission fluid level (after a 10 min drive) and it was less then 1/4 qt low.
In the last 2 months I have done some work, replaced both drive shafts (purchased at Napa) and front wheel bearings (purchased at zzperformance). Both drive shafts were starting leak grease all over the place and I just replace the wheel bearing because everything was already apart (preventive maintenance if you will).
I have never changed the transmission fluid or filter. That is something I was going to do to see if it would help. Is that a possibility?
I am not getting any errors on the pcm. I know that's not a lot to go by but what other things might cause those symptoms?
Thanks.
