Dramatic gear change on 2001 Mazda 626

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When my vehicle shifts from first to second or second to third gear, the rpm builds up until the gear changes and there is a significant jerk in the car at the time it changes gear. The car has a 100K miles on it. Why would this be?

First thing to check is your transmission fluid level, If its low it will slip when changing gears.
I see a turbine speed sensor available from the dealer and the labor to change this is .6 of an hour
it sounds exactly like the transmission in my van but I had it rebuilt and all is's whats happening to yours you are actually skipping over 2nd gear and when it finally catches third you feel a jerk and since 2nd gear is usually paired with 4th or overdrive so 4th is getting toasted to.........sorry about your luck!!!!!!!
