Okay, what a happened is that a stoplight it was my turn to go as I started to go some one ran the red light so I floor it. A little later I felt the gears were not all shifting. It goes to 35 miles and then no more gears, but if I put it on over drive it goes up to 80 plus changing only one time.

Thank you for your time.

Good morning,

This could be many issues. Testing needs to be done to find out what has failed.

There are procedures I attached that should be done to narrow the area of failure. Chances are you have something that failed internally in the transmission.

Line Pressure Test

CAUTION: Carry out the Line Pressure Test prior to carrying out the Stall Speed Test. If line pressure is low at stall, do not carry out the Stall Speed Test or further transaxle damage will occur. Do not maintain wide open throttle in any gear range for more than five seconds.

NOTE: Certain sensor failures may cause high PC, FMEM (Failure Mode Effect Management) actions. Make sure that self test and electrical repairs have been carried out, or test results may be incorrect.

This test verifies that the line pressure is within specifications.
1. Connect pressure gauge to the line pressure tap.

2. Start engine and check line pressures. Refer to the following Line Pressure chart to determine if line pressure is within specifications.

3. If line pressure is not within specifications, refer to line pressure diagnosis chart for line pressure concern causes.
