Two things have recently started with my transmission, 1st on a cold start and shifting from park to drive you hear a clank noise coming from the transmission. 2nd While driving it feels like the transmission skips 3rd gear, it goes from 1st to 2nd smooth then all of a sudden it drops in this low gear with a thump, assuming that this is 4th gear. Now if you keep your foot on the gas to stretch the gears out it will go into 3rd. To describe the feeling better is like if u were in manual and u went from 2nd to 4th gear the idles drop low and the car take a while to pick up speed in the low gear. This is what it does.
thanks for your time

Bulletin No: 01-8-1
Date: April 30, 2001
ISSUE
Some vehicles equipped with a 3.0L Vulcan engine built prior to 3/1/2001 may exhibit a perceived:
High idle when shifting from Park/Neutral to Drive/Reverse on a cold start
High creep speed in Drive or Reverse
Rough and harsh shifts while driving when cold
Cold engine harsh Park/Neutral to Drive/Reverse engagements
Engine rpm surge during a 2-3 coasting upshift at approximately 40 km/h (25 mph)
This may be caused by the calibration of the Powertrain Control Module (PCM).
ACTION
Verify condition. If normal diagnostics cannot pinpoint condition, reprogram the PCM. Refer to following Service Procedure for details.

SERVICE PROCEDURE
1. Reprogram the PCM to the latest calibration. Refer to the PCM Calibration Information Chart in Fig. 1 for applications.
NOTE: If using a New Generation Star (NGS) tester to reprogram the PCM, the NGS may ask "Would You Like To Modify Any PCM Parameters?" Answer "NO" to this question. This will prevent changes to the tire size and axle ratio. If "YES" was inadvertently selected, it may be necessary to enter 797 for tire size and 3.47 for the final drive axle ratio.
2. Advise the customer that it may take several drive cycles (dependent on cycle) before the PCM will completely adapt to the new calibration.
Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. See Fig. 2. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
