All Models

Check transmission fluid level every 15,000 miles or 24 months. Transmission fluid reservoir is independent from the transmission. Normal operating conditions service interval information is not available for transmission fluid. Under severe conditions such as trailer towing, police, taxi, local delivery service or operating under dusty conditions, replace transmission fluid every 15,000 miles or 12 months.

Transaxle/Transmission

1. Drive vehicle until engine and transmission reach normal operating temperature. Park vehicle on level surface and apply parking brake. With engine idling and brakes applied, move gearshift lever through all positions ending in "P" position.
2. Check fluid level on transmission dipstick. Fluid level should be in HOT range marked on dipstick. Add proper type of fluid if necessary. See «RECOMMENDED FLUID»(ref-8672-S15747363472000091200000) . DO NOT overfill transmission.

Transaxle Differential (Avalon, Camry, Celica (1999) & Corolla 1.6L)

Remove filler plug. (Scheme 8)- (Scheme 10). Fluid should be level with bottom edge of filler plug hole. If fluid is low, fill with proper type fluid until fluid is level with filler plug opening. See RECOMMENDED FLUID. Reinstall filler plug.

Transfer Case (Land Cruiser, Tacoma, Tundra & 4Runner)

Remove filler plug located on rear of transfer case. Fluid should be level with bottom edge of filler plug hole. If fluid is low, fill with proper type fluid until fluid is level with filler plug opening. See RECOMMENDED FLUID . Reinstall filler plug.

Transfer Case (RAV4)

Park vehicle on level surface and apply parking brake. Check fluid level on transfer case dipstick. Fluid level should be in the LOW to HIGH range. Add proper type of fluid if necessary. See RECOMMENDED FLUID . DO NOT overfill transfer case.

Transaxle & Transmission

1. Raise and support vehicle. Drain transmission fluid into proper container. If replacing transmission oil strainer, remove transmission oil pan and gasket.
2. Remove bolts, transmission oil strainer and gasket (if equipped). Thoroughly clean transmission oil pan. Install NEW gasket (if equipped), install transmission oil strainer. Tighten bolts to specification. See «TORQUE SPECIFICATIONS»(ref-8672-S23979257772000091200000). (Scheme 11)and (Scheme 12). Fill transmission through dipstick tube to specified capacity using recommended fluid. See «RECOMMENDED FLUID»(ref-8672-S15747363472000091200000).
3. Ensure vehicle is on a level surface. Apply parking brake. Start engine and apply brakes. Bring engine to operating temperature. Move gearshift selector through all gears, ending in Park. Recheck fluid level, add as necessary. DO NOT overfill.

Scheme 11

Scheme 12

1. Remove filler plug located on rear of transfer case. Remove drain plug from bottom of transfer case. Allow fluid to drain. Reinstall drain plug.
2. Fill transfer case through oil filler plug hole to specified capacity using recommended fluid. See «RECOMMENDED FLUID»(ref-8672-S15747363472000091200000) . Ensure fluid is level with bottom edge of filler plug hole. Reinstall filler plug.

Land Cruiser

1. Apply parking brake. Loosen nut on shift lever on side of transmission. (Scheme 13) Move control shaft lever fully toward rear of vehicle.
2. Move control shaft lever 2 notches to Neutral position. Set gearshift lever to Neutral position. While holding control shaft lever slightly toward Reverse position, tighten control rod nut.
3. Start engine. Ensure vehicle moves forward when shifting gearshift lever from "N" to "D" position, and rearward when shifting to "R" position.

Scheme 13

Tacoma & 4Runner With Floor Shift

1. Apply parking brake. Loosen nut on shift lever on side of transmission. (Scheme 14) Move control shaft lever fully toward rear of vehicle.
2. Push control rod forward 2 notches to Neutral position. Set gearshift lever to "N" position. Tighten nut for control rod at gearshift. While holding control shaft lever slightly toward "R" position, tighten control rod nut.
3. Start engine. Ensure vehicle moves forward when shifting gearshift lever from "N" to "D" position, and rearward when shifting to "R" position.

Scheme 14

Tacoma With Column Shift

1. Apply parking brake. Loosen swivel nut on manual shift lever on side of transmission. (Scheme 15) Move manual shift lever downward to Park position.
2. Move manual shift lever upward 2 notches to Neutral position. Set gearshift lever to "N" position. While holding manual shift lever slightly toward "R" position, tighten swivel nut.
3. Start engine. Ensure vehicle moves forward when shifting gearshift from "N" to "D" position, and moves rearward when shifting to "R" position.

Scheme 15

PARK/NEUTRAL SWITCH

Note. Park/Neutral switch may also be referred to as Park/Neutral Position (PNP) switch.

1. Check if engine can be started with shift lever only in "N" or "P" positions. If adjustment is needed, loosen park/neutral switch retaining bolt(s). Position gearshift in Neutral. Align neutral line on park/neutral switch with groove on shaft. (Scheme 16)or (Scheme 17).
2. Hold park/neutral switch in this position and tighten retaining bolt to specification. See «TORQUE SPECIFICATIONS»(ref-8672-S23979257772000091200000). Ensure vehicle only starts with shift lever in "P" or "N" position.

Scheme 16

Scheme 17

Avalon, Camry, Corolla, RAV4, Sienna, Solara, Tacoma, Tundra & 4Runner

1. Ensure accelerator pedal is in released position and throttle valve is fully closed. No slack should exist in throttle valve cable at throttle body. Measure distance between outer cable and stopper on throttle valve cable. (Scheme 18)
2. Loosen adjusting nuts on throttle valve cable. Tighten or loosen adjusting nuts until proper distance is obtained. On 2000 Avalon models, distance should be.031-.059" (.80-1.50 mm). On all other models, distance should be 0-.04" (0-1.0 mm). Tighten adjusting nuts. Recheck distance once adjusting nuts are tightened.
