(3) With selector lever in "P"1Park) and parking brake applied,
start engine. =
(4) Engine should be running at idle speed. Trai%missi& -7
should be warmed-up suf%ently [fluid temperatcre 50 to I'
80°C (I 20 ta: 18O"FjI.
(5) Move selector lever sequentially to every posItion to till
torque converter and hydraulic circuit wrth fiuld, then place ~~
lever in "N" (Neutral) posItIon.
(6) Check to see rf fluid level IS In the range indrcated on ii
dipstlck.
If it is low, add ATF until level reaches that range. -1
Transmission fluid: DEXRON II type
Low fluid level can cause a variety of troubles because It
allows pump to take in art- along with fluid. Air trapped in
hydraulic circuit forms bubbles which make fluid spongy.
Therefore, pressure-s will be erratic, and causes delay of 1
shifting, and slippage ot clutch and brake.
Improper filling can ralSe fluid level too high. When .mT
transmission has too much fluid, gears churn up foam and
cause same conditions which occur with low fluid level, ~_
resulting in accelerated deterioration ot ATF.
In either case, air bubbles can cause overheating, fluid z
(j%ldatlon, and varnishing,. which can lntertere with normal
valve, clutch, and servo operation.
Foaming can also result in fluid escaping from transmission ._
vent where it may be mistaken. tar a leak. Along with fluid
~~
level, It is impdnant to check the condition of the fluid. ~.
When fluid smells burned, It
IS
contaminated vth metal c
bushing or friction material particles, and a complete ~-
transmlsslon overhaul is needed. Be sure TV examrne fluid
on dipstick closely. If there is any doubt about Its condition, me
drain out sample for double check. After ~fluid has been 11
checked, seat dipstick tully to seal out water and dirt. _
