Hi,I presently own a 2001 dodge caravan with a 3.8 lit motor AWD .I am having a problem with a engine vibration that starts out at aprox 1800 RPM then goes to 2200 RPM .it like a partis vibrating and goes right through the complete car .its worse under load.It have been to about 6 dealers ,
In my opinion there are two vibrations in my vehicle ,one is engine related and one is driveline related .
it has had 2 sets of tires put on,I set of rims ,8 drive sharts ,(2 front)4 rear and 2 front to back,.
I feel at certain speeds its from the engine and the driveline transmits it to the body.(it feels like a miss)when it goes into lock up and it seems to cut out as you drive it .It has not shown up on the computer (check eng Light ) or the DRB.
Would you think the flex plate is busted.I was thinking there is a issue with the torque converter,at its stall speed and it just happens to create some of these issues.
thanks for all your help
