Hell Yeh! That's one thing that killed our E36 BMW 320i's tranny before. When we got the car (2nd hand), i asked the dealer to change the ATF (standard practice of ours)... dehins daw at lifetime na siya ("sealed" ika' nga ng SA) so we took his word for it, being supposedly the guy with the knowledge on that. A few months later the tranny went into safe mode and the warning light went on. When they brought it down, we were told there was corrosion inside caused by water contamination. SOmething i feel could have been avoided if the tranny oil was changed.

When driving normally, just keep the car in "D" with the o/d on. If you want to have more engine braking control (i.e. mountain roads, two lane highways, overtaking, etc), then shift manually between the gears. Nothing beats practicing and trying it out yourself.

AVOID:
- shifting to R while the car is moving forward
- shifting from N to D while revving the engine at stop

Typical change period is every 40,000km but i prefer to do it every 20,000km given our drving and weather conditions. MAsakit sa bulsa ang magka a/t problems.

sabi ng frend ko "off" lang daw ang OD kapag city driving at "on" na lang
kapag highway. isa pa daw magandang maintenance sa auto tranny
is to shift to neutral kapag stop sa traffic.
last time na hindi ako nagsi-shift to neutral kapag naka-stop parang
nagba-vibrate ang kotse. after na nag-neutral na ako nawala na
ang vibration.

tama po dapat naka-neutral ka kapag naka-stop para lumamig yung ATF......

pansin ko din kse, bagal mag-accelerate kung sa D lang nakalagay. any comments?

and how about fuel-saving tips? is it okay to put to neutral approaching stops or traffic?

sir jiggs,

am not sure abt the L1 L2 to D while accelerating, but i believe its not a good habit to shift to N from D while approaching a stop or traffic light. and fuel saving, going steady with your speed and rpm should do the trick, but i guess that goes for all cars,MT and AT..

when you want to go fast on a standstill, dont rev the engine then engage to drive! this will wreck your torque converter.

e ask ko lng mga sirs...pag stop-and-go traffic at pag ganito ginawa mo,may possibility bang uminit naman ang mga clutch plates o di kaya madali ito(clutch plates) mag-worn-out?

I think its not a good habit to do it each and everytime you shift.

Mas oks pa na iturn off mo yung OD para hindi siya pupunta sa 4th o 5th. kung oovertake ka o mageengine brake ka.

Mabagal? siguro tapakan mo lang ng todo yung accelerator pedal, kasi from my experience pag tinapakan ko ng todo mag shishift siya at around 4000+ rpm, pag incline minsan umaabot ng 5000+ rpm. Pag alalay sa tapak aroung 2000 -2500 rpm siya nagshishift. (honda a/t).

Sometimes it also depends sa engine mo kung maliit siya talagang medyo mabagal lalo na pag paahon.

Putting it in neutral siguro pag full stop na, I'm not sure pero di ba A/T umiikot lang yung fluid pag nakaengage, so in effect mawawala or mababawasan yung atf na umiikot pag neutral mo siya while the vehicle is still moving. (i would rather spend or waste gas than to have a problem sa A/T, kasi mas masakit sa bulsa)

Experts correct nyo na lang kung merong mali

dont use expensive shoes while driving with AT, mauubos agad yung right shoe. lower right corner. especially nike shox

**rudy123** · January 7th, 2005 09:17 AM

bakit kaya di nila ginawang sa left side na lang ang preno para
parehong paa ang gumagalaw?

isa pang disadvantage ng hindi nagnu-neutral kapag stop and go
traffic ay siguradong sasakit ang paa mo sa katatapak sa preno

This was taught to us in driving school back in High School sa tate.

1. Never place your tranny on Reverse if the car hasn't come to a complete stop.
2. When shifting from Reverse (R) to Drive (D) always come to a complete stop first before changing gears.
3. Only use (2) and (1) if you need ENGINE BRAKE. So accelerating from 0 to whatever speed, don't do it manually..remember...its an automatic. Those two gears are meant to slow down the vehicle on an downhill slope.
4. Try to avoid shift from D to N if the wait is not that long. Just use your brake. This stresses out your gears if you always switch gears from D to N (remember clutch free sya)
5. If you want to SPEED up, just step on the accelarator pedal. The tranny will downshift to the proper gear. To give more power, you have the option to turn off the overdrive.
6. Some auto tranny has sports mode or normal mode. Sports mode=longer speed to gear ration while normal mode=short speed to gear ratio (that means you save on gas).
7. Remember if the overdrive is off, you will consume more gas. (just look at your counters, if the OD is off, it lights up, if OD is on no indicator)
8. Always make sure to have the right ATF and change as prescribed by the manufacturer.
