  4.  
  5. Remove the transmission oil dipstick, and the bolt holding the dipstick tube (if it is accessible).
  6.  
  7. Raise the vehicle and safely support it with jackstands.
  8.  

If a floor pan reinforcement is used, remove it if it interferes with driveshaft removal or installation.

  1. Disconnect the speedometer cable at the transmission.
  2.  
  3. Disconnect the shift linkage at the transmission.
  4.  
  5. Disconnect all electrical leads at the transmission and any clips that hold these leads to the transmission case.
  6.
