P1811
The transmission pressure is modified by an adaptive modifier which controls the shift execution time. This diagnostic tests the time required to accomplish the shift. If the shift takes longer than 0.65 seconds and the adaptive modifier cannot shorten this time, then a counter increases by one.
If the PCM detects a counter value of 2 during one trip, then DTC P1811 sets. DTC P1811 is a type C DTC
The 1-2, 2-3 or 3-4 shift is longer than 0.65 seconds, twice in one trip.
?€¢
Ask the customer about possible overloading, exceeding the trailer towing limit, or towing in overdrive.


?€¢
Ensure that the current PCM calibration is correct for the final drive ratio.


  1. Use the scan tool snapshot mode in order to record the shift times.
  2. Drive the vehicle in D4 in order to obtain a 1-2, 2-3 and 3-4 upshift.
  3. Record the shift times.
Did all the shift times exceed the specified value?
0.65 seconds
Perform the Line Pressure Check Procedure.
Refer to the Line Pressure Check .
Is the line pressure within specifications?

You may want to take this to the dealer !

When shifting from second to thrid it has a skipping or bucking.drop transmission pan,no metal or shavings in pan


You should have the computer scanned at a transmission shop or a dealership. If you get a code P1811, that is the 'max adapt long shift' code. That means that the Electronic Pressure Control solenoid may be going bad. Normal wear and tear on the clutch material can also cause this code. Basically, it means that the transaxle is taking longer than 0.65 seconds to shift, and the computer commands maximum line pressure to avoid burning out the clutches. I have had good success with installing a shift kit on several of these transaxles (4T65e) to remedy this problem with no further issues. Visit www.transgo.com and look for distributors in your area. The shift kit you need is the SK 4T65e shift kit. The kit comes with very good instructions. It is not a difficult job. If you can drop the pan and change your own fluid, you can install this kit.
