At work today an apprentice tech offered to do my plugs, wires, cap, rotor and coil. To do the pass side 3 plugs he put it up on a lift.

After the cars trans was slipping badly on the way home (speeds up to 100 km/h and residentail)

After sitting awhile the car dorve pretty normal.
I did check the trans fluid and it was down maybe a litre.

My question--couold he have bumped something underneath the car or up by the coil (by intake manifold) and just how wired would my trans act if it was low on fluid?

I'll drive to work and see how it behaves.

 

Low fluid will definitely make your tranny slip (personal experience); slowly, add a little bit of fluid until you're within operating range, and take it for a drive and see how it does. Make sure you don't overfill though because it's a heck of a lot easier to add ATF than to remove it.
