Gears slipping when accelerating Inspection $79.99 - $99.99 Get a Quote

Hello - the lack of an upshift from 1st to 2nd could be dirty, burned fluid or clogged filter, or a failed Shift Solenoid "A". Low fluid level and low electrical system voltage can also make the transmission misbehave as you are experiencing. I would recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
