These have a limited liftspan...by shifting in and out of drive, these components will wear out faster and hence you need to change.2) Engage the tranny in gear would allow the ATF to go aound the transmission instead of sitting still building heat.If you want to prolong your tranny...the usual stuff like coming to a complete stop before shifting to R etc...beside this, make use of the other ratios in your auto box by manually shifting them thru 1,2,3,4 & D instead of leaving in D and drive. There are a number of clutch plates in the transmission and each ratio has its own clutch...by using only D...the higher wear on that plate is to be expected. Imagine this...if the clutch plate is to last only 80,000km...you can double that by using another ratio like 4 or 3 (depending on your box is 4speeder or 5 speeder).Try this...when you are driving in town, if your box is a 5 speeder, chances are they will never get to shift into 5th ratio as speed is slow. So since its gonna be stuck in 4th...why not shift into 4 and drive...when the speed picks up, then shift into D to make the box jump into the final ratio. You will find that your car has better pickup...cos the clutch plate is almost brand new (ie if you have never shift into other ratios other than D)Most of the mech told me that when they take apart a tranny...they always find 3 sets of good condition clutch and 1 worn out one (4 speeder) and you can prob guess which clutch worn out first rite ?</blockquote>
