14-3
The automatic transmission is a combination of a 3-element torque converter and triple-shalt electronically controlled
automatic transmission which provides 4 speeds forward and 1 speed reverse. The entire unit is positioned in line with
the engrne.
Torque Converter, Gears, and Clutches
The torque converter consists of a pump, turbine, and stator, assembled in sigle unit. The torque converter is connected to
the engine crankshaft so they turn torether as a unit as the engine turns. Around the outside of the torque convener is a
ring gear which meshes with the starter pinion when the engine is being started. The entire torque converter assembly
serves as a flywheel while transmitting power to the transmission mainshaft.
The transmission has three parallel shafts; the mainshaft. the countershaft, and the sub shaft. The mainshaft is in-line with
the engine crankshaft.
The mainshaft includes the 1st, and 2ndl4th clutches,and gear for 3rd, 2nd, 4th, reverse, and 1st. (3rd gear is integral with
the mainshaft, while reverse gear is integral with the 4th gear.)
The countershaft includes the 3rd clutch and gears for 3rd,2nd, 4th, reverse, 1st, and parking. Reverse and 4th gears can
be loched to the countershaft at its center,providing 4th gear or reverse, depending on which way the selector is moved.
The sub-shaft includes the 1st-hold clutch and gears fo 1st and 4th.
The gears on the mainshaft are in constant mesh with those on the countersahft and sub-shaft.When certain combinations
of gears in the transmission are engaged by clutches. power in transmitted from the mainshaft to the countershaft via the
sub-shaft to orovude oil, lo'1. E, E. and E.
Electronic Control
The electronic control svstem consists of the Transmission Control Module (TCM), sensors, and four solenoid valves.
Shilting and lock-up are electronically controlled for comfortable driving under all conditions.
The TCM is located below the dashboard, behind the lelt side kick panel on the driver's side.
Hydraulic Control
The valve bodies include the main valve body, the secondary valve body, the regulator valve body, the serbvo body, and
the lock-up valve body, through the respective separator plates, They are bolted to the torque converter housing,
The main valve body contains the manual valve, the 1-2 shift valve, the 2-3 shitt valve, the Clutch Pressure Control
lCPC) valve, the 4th exhaust valve, the reliel valve, and the ATF pump gears.
The secondary valve body contains the 4-3 kick-down valve, the 3-2 kick-down valve, the 2-3 orifice control valve, the
3-4 shift valve, the orilice control valve, the modulator valve, and the servo control valve.
The regulator valve body contains the pressure regulator valve, the lock-up control valve, the torque converter check
valve, and the cooler check valve.
The servo body contains the servo valve, which is integrated with shift fork shaft, the throttle valve B, and the accumula-
tors.
The lock-up valve body contains the lock-up shift valve and the lock-up timing B valve, and is bolted to the regulator valve
ooqy.
Fluid from the regulator passes through the manual valve to the various control valves.
Shift Control Mechanism
Input to the TCM from various sensors located throughout the car determines which shift control solenoid valve should
be activated. Activating a shitt control solenoid valve changes modulator pressure, causing a shift valve to move. This
pressurizes a line to one ol the clutches, engaging that clutch and its corresponding gear.
Lock-uD Mechanism
In @ position, in 2nd, 3rd and 4th, and @ position in 3rd, pressurized fluid can be drained lrom the back oI the tor-
que converter through a fluid passage, causing the lock-up piston to be held against the torque converter cover. As this
takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together with hydraulic control, the TCM
optimizes the timing of the lock-up mechanism.
The lock-up valves controlthe range of lock-up according to lock-up control solenoid valves A and B, and throttle valve B.
When lock-up control solenoid valves A and B activate, modulator pressure changes. Lock-up control solenoid valves
A and B are mounted on the torque converter housing, and are controlled by the TCM.

NOTES
See flushing procedure, page 14-172 and 173.
B.Set idle rpm in gear to specilied idle speed. lf still no good, adjust motor mounts as outlined in enginesection of service manual.
c.lf the large clutch piston O-.ing is broken, inspect the piston groove for rough machining.
D.lf the clutch pack is seized or is excessively worn, inspect the other clutches lor wear, and check the
orifice control valves and throttle valves for free mov€ment.
E.lf throttle valve B is stuck. insDect the clutches for wear.
lf the 1 - 2 shift valve is stuck closed, the transmission will not upshitt. lf stuck open, the transmissionhas no lst gear.
H.lf the 2-3 orilice control valve is stuck, inspect the 2nd and 3rd clutch packs for wear.
lf the orifice control valve is stuck. inspect the 3rd and 4th clutch packs for wear.
J.lf the clutch pressure control valve is stuck closed, the transmission will not shift out oI 1st gear.
lmproper alignment or main valve body and torque converter housing may cause ATF pump seizure.
The symptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
lf the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differentialpinion shaft. lf both are OK and no cause for the contamination is found, replace the torque converter.
M.lf the 1st clutch feed pipe guide in the right side cover is scored by the mainshaft, inspect the ball bear-
ing lor excessive movement in the transmission housing. lf OK, replace the right side cover as it is dent-
ed. The O-ring under the guide is probably worn.
N.Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged.lf the 4th feed pipe is damaged or out of round, replace the right side cover.Replace the sub-shaft il the bushing for the 1st-hold teed pipe is loose or damaged.lf the 1st-hold teed pipe is damaged or out of round, replace it.
Replace the mainshaft iI the bushing for the lst feed pipe is loose or damaged.lf the 1st leed pipe is damaged or out of round, replace it.
A worn or damaged sprag clutch is mostly a result of shifting the transmission in El or LDll position
while the wheels rotate in reverse, such as rocking the vehicle in snow.
P.Inspect the trame for collision damage.
Inspect lor damage and wear:1. Reverse selector gear teeth chamfers.2. Engagement teeth chamfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.4. Differential pinion shaft tor wear under pinion gears.
5. Bottom of 3rd clutch for swirl marks.Replace items 1 . 2, 3 and 4 iI worn or damaged. lf transmission makes clicking, grinding or whirringnoise, also replace mainshaft 4th gear, reverse idler gear, and countershatt 4th gear in addition to '1,
2,3or4.It differential pinion shalt is worn, overhaul differential assembly, and replace ATF strainer, and thoroughly
clean transmission, tlush torque conveder, cooler and lines.lf bottom ot 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and final
onven qear.
R.Be very careful not to damage the torque converter housing when replacing the main ball bearing. You
may also damage the ATF pump when you torque down the main valve body. This will result in ATFpump seizure if not detected. Use proper tools.
S.Install the main seal llush with the torque converter housing. lf you push it into the torque converterhousing until it bottoms out. it will block the fluid return passage and result in damage.
T.Harsh downshifts when coasting to a stop with zero throttle may be caused by a bent-in throttle valve
retainer/cam stopper. Throttle cable adjustment may clear this problem.
Throttle cable adjustment is essential tor proper operation ol the transmission. Not only does it affectthe shift points if misadjusted, but also the shift quality and lock up clutch operation.A cable adjusted too long will result in throttle pressure being too low for the amount of engine torqueinput into the transmission and may cause clutch slippage. A cable adjusted too short will result in toohiqh throttle pressure which may cause harsh shifts, erratic shifts and torque converter hunting.
