I have a 98 4Runner 4-cyl with an automatic transmission. It has a 154,000 miles. A few days ago I got the transmission fluid changed in the truck. On two separate occasions my wife has noted from a take-off that there seems to be a 'jerk' before it takes off. She describes it as what you feel when you first put a car in gear before the tranny really 'settles' on the gear. What could cause this? Should I immediately take it back to the shop?

TIA!

Its possible the ATF level isn't right.

I would, just in case.

"When the filter is replaced it has to be done with care. There are three ports on the filter where the fluid passes into the transmission. Each has its own gasket. It is common for at least one of these gaskets to slip out of position during installation and cause air to leak into the pump pick up causing it to break suction and loose output pressure. The problem usually presents after hard stops and the transmission will not complete its shift into first. Then when you go to pull off the engine revs and then the transmission engages very harshly with a tire chirp. Just make sure they are all properly positioned during replacement."

Did the tranny shop drop the pan and mess with the filter?
