Re: What will i need to do to get a new transmition fluid...
Procedure pasted below. Please let me know if you have questions, and thanks for using FixYa.
Drain, Refill & Filter Service
-
The fluid should be drained when warm so contaminants are in suspension in the transaxle fluid.
-
Raise and safely support the vehicle on safety stands.
-
Place a suitable drain pan under the transaxle fluid pan.
-
There is no drain plug for changing the transaxle fluid, so fluid
change on most automatics is messy. Draining the fluid involves
loosening some bolts, removing others, and, after the pan is loosened,
letting the fluid run out from the joint between the pan and gasket and
the transaxle body. Use a drain pan with a large enough opening to
accommodate draining the fluid from a large section of the pan.
-
There are twenty oil pan bolts. Loosen and remove only the bolts from the front and sides of the pan.
-
Loosen the rear bolts about four turns.
WARNING
Do not pry between the oil pan and the aluminum transaxle case. A
prying tool could mark, scratch or gouge the gasket sealing rail making
it impossible for the replacement gasket to provide a satisfactory seal.
-
Lightly tap the pan with a rubber mallet to loosen and allow the fluid to drain.
NOTE
If the transaxle fluid is very dark or has a burnt smell,
transaxle damage is indicated. Have the transaxle checked
professionally.
-
Remove the remaining bolts, the pan and the gasket. Hold the pan
level to keep a small amount of fluid in the bottom. This allows you to
check the sediments in the pan for contaminants. Remove the pan and set
aside.
-
The transaxle oil filter has a small neck that is a press-fit into
the transaxle case. It should pull straight out. A little careful
prying may be required. The rubber grommet that accepts the neck on the
filter will likely remain in the transaxle case. Use a small screwdriver
to carefully remove the seal. Use care not to damage the case sealing
surface.
-
Inside the pan should be a small magnet. Inspect the oil pan
magnet for small bits of steel. The factory places the magnet here to
trap stray metal particles. Excessive amounts of steel shavings indicate
internal transmission damage. A small amount of sediment in the pan is
normal as the friction elements wear.
-
If desired, use side cutters to open up the transaxle oil filter
assembly by cutting or prying the metal crimping away from the top of
the filter and by pulling the filter apart. Inspect the filter for
excessive amounts of the following: clutch plate assembly fiber
material, indicating clutch distress; bronze slivers, indicating bushing
wear; steel particles, indicating internal transaxle wear.
To install:
-
Clean all parts well. Clean all traces of old gasket off of the
oil pan gasket rail as well as the sealing surface on the transaxle. Use
care not to damage the sealing surface on either area.
-
Inspect the oil pan for damage to the sealing surface and dents or cracks in the pan.
-
If the oil filter seal came out of the case, install it using a
socket as a driver. Gently tap in with a plastic mallet. Using the same
plastic mallet, gently tap the filter neck in place.
-
The design of the steel-core factory gasket is such that it may be
reusable, if not bent or otherwise damaged. Note that most replacement
transaxle oil filters come with a new gasket. Lay the oil pan gasket on
the pan and install the pan to the case. Normally, no sealer is used.
Start a few bolts at the ends of the pan to hold it and to keep the
gasket from moving out of position. Install all 20 bolts and tighten to
97 inch lbs. (11 Nm). Do not overtighten or the gasket could be squeezed
out of position and/or the bolt threads in the aluminum transaxle case
could be damaged.
-
Lower the vehicle to the floor.
-
To refill the transaxle from just a bottom pan removal, 7.4 quarts
of DEXRON® IIE or DEXRON® III will be required. Use a funnel to reach
the filler/dipstick tube. Use care not to spill fluid in the engine
compartment.
-
Check for leaks.
