25. Disconnect the vacuum tubes from the vacuum chamber on the left side of the gearbox (see fig. The location of the vacuum chamber on the left side of the automatic transmission). Disconnect the remaining vacuum tubes from the gearbox housing. Remove the tubes from the mounting brackets or brackets on the gearbox housing. On some models, to remove the vacuum tubes from the gearbox, you must first disconnect them from the intake manifold in the engine compartment.
26. Remove the mounting brackets and remove the shift rod from the gear select lever on the gearbox and from the bottom of the selector lever.
27. Unscrew the connecting bolts and disconnect the supply and return pipes of the transmission fluid heat exchanger from the gearbox (see fig. An arrangement of a connecting bolt of fastening of a tube of the heat exchanger of transmission liquid). Remove the o-rings and plug the ends of the tubes and the openings in the gearbox to prevent dirt from entering.
28. Unscrew the transmission fluid heat exchanger tube brackets from the transmission from the engine and move the tubes to the side.
29. Release the retaining clip and remove the transmission fluid dipstick.
30. Remove the bolt securing the transmission fluid dipstick tube to the transmission case. If equipped, remove the transmission-to-engine bolt securing the transmission fluid dipstick tube. Remove the transmission fluid dipstick tube from the transmission (see fig.
