ive got an auto 92 h23a1, just wondering why when the car is in neutral or park. the car is fine, however, when i put it on D4,D3,2 or 1 and te foot is on the brake, the ca rumples like crazy....also when i change the gears and as im driving, i can feel the car jump forward....it kinda wierd....and suggestions would be helpful

 

Check your motor mounts, sounds like one may be broken.

 

its so easy even a cave man can do it

 

LOL! Good one. Yeah check your motor mounts first.

 

 

Also check your engine idle speed isn't too high or the auto will try and drive the wheels, and make sure the ATF liquid is within service limits, if not change and make sure your at the correct fluid level.
