NOTES
A.See flushing procedure, page l4-168 and 169.
B.Set idle rpm in gear to specitied idle speed. lf still no good, adiust motor mounts as outlined in engine
section of service manual.
lf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
lf the clutch pack is seized or is excessively worn, inspect the other clutches Jor wear, and check the
orifice control valves and throttle valves for free movement.
E.It throttle valve B is stuck, inspect the clutches for wear.
lf the 1-2 shift valve is stuck closed, the transmission will not upshift. lI stuck open, the transmission
has no lst gear.
H.lf the 2-3 orifice control valve is stuck, inspect the 2nd and 3rd clutch packs for wear.
ll the orifice cont.ol valve is stuck, inspect the 3rd and 4th clutch packs for wear.
lf the clutch Dressure control valve is stuck closed, the transmission will not shilt out of 1st gear.
K.improper alignment or main valve body and torque converter housing may cause oil pump seizure. The
symptoms ale mostly an rpm-related ticking noise or a high-pitched squeak.
L.ll the ATF strainer is ctogged with panicles of steel or aluminum, inspect the oil pump and ditferential
pinion shaft. lt both are OK and no cause lor the contamination is found, replace the torque converter.
M.lf the 1st clutch feedpipe guide in the right side cover is scored by the mainshaft, inspect the ball bear-
ing for 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.ReDlace the mainshstt if the bushing for the 4th feedpipe is loose or damaged.
It the 4th feedpipe is damaged or out ot tound, replace the right side cover'
Replace the subjshaft it thtbushing for the 1st-hold Jeedpipe is loose or damaged.
lf the 1st-hold feedpipe is damaged or out of round, replace it.
Replace the mainshaft if the bushing lor the 1st feedpipe is loose or damaged.
lf the lst feedpipe is damaged or out ot round, replace it.
o.A *o- r, da."s"d "p-g clutch is mostly a result of shifting the transmission in El or Lq! position
while the wheels rotate in reverse, such as rocking the car in snow.
P.InsDect the frame for collision damage.
o.Inspect for damage or wear:
1. Reverse selector gear teeth chamfers.
2. Engagement teeth chamters of countershaft 4th and reverse gear.
3. Shift fork for scutt marks in center.
4. Differential Dinion shaJt for wear under pinion gears.
5. Bottom of 3rd clutch for switl marks.
Replace items 1 , 2, 3 and 4 it worn or damaged. lf transmission makes clicking, grinding or.whirring
noise, atso replace mainshaft 4th gear and reverse idler gear and countershaft 4th gear in addition to
1,2,3ot4.lf ditiersntial Dinion shaft is worn, overhaul differential assembly, and replace ATF strainel, and thoroughly
clean transmission, tlush torque convertet, cooler and lines.
lf bottom of 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and tinal
driven gear.
R.Be wry careful not to dsmage the torque converter housing when replacing the main ballbearing. You
may al;o damage the oil pump when you torque down the main valve body. This will result in oil pump
seizure it not detected. Use proper tools.
qInstall the main seal tlush with the torque converter housing, lf you push it into the torque converter
housing until it bottoms out. it will block the oil return passage and result in damage.
T,Harsh do\/vnshiJt"\./l,'hen coasting to a stop with zero th.ottle may be caused by a bent-in throttle valve
retainer/cam stopper. Throttle cable adjustment may clear this problem.
ifuitle cable adjustment is essential for proper operation of the transmission. Not only does it affect
the shift points if misad,usted, 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 torque
input into ihe trsnsmission and may cause clutch slippage. A cable adjusted too short will result in too
hi;h throttle pressure which may cause harsh shitts, erratic shrfts and torque con

Pressure Testing
a While testing, be caretul of the rotating flont wheels.a Make aura litts, jacks, and sat€ty stands alo placedplop6rly {see section 1}.
CAUTION: Betore t€sting, be sure the transmission fluidis tilled to rh6 ploper l€vet.
1. Raise the car (see section i),
2. Warm up the engine {the cooling fan comes onl, thenstop the engine and connect a tachometer.
3. Connect the oil pressure gauge to each inspectionholels).
TOROUE: 18 N.m (1.8 kgf.m, 13 tbf.fr)
CAUTION: Connect ths oil prsssure gauge s€cur€_ly; be sule not to allow dust and other foleign pani_cl6s to 6nt€1 th€ inspection holo.
