1973 CJ-5 jeep with 3 speed manual transmission is locked in gear

Jeeps have an ECM ( Electronic Control Module) on the transmissions as well as the engine.

rtm? no symptoms so i must guess, ill say , cant shift. and is not park lock out causing that.
want to read the manual or me to you.'?
ill guess you.

click 1996 to 2001
it replaces like all cables do
detach both ends and remove it. if clamps seen those too.
what matters is adjustment is needed.

some have 2 cables, one to gear box and one to ignition switch.
Chapter 21, page 150 states
REMOVAL
(1) Shift transmission into Park.
(2) Remove shift lever bezel and necessary console
parts for access to shift lever assembly.
(3) Disconnect cable at shift lever and feed cable
through dash panel opening to underside of vehicle.
(4) Raise vehicle.
(5) Disengage cable eyelet at transmission shift
lever and pull cable adjuster out of mounting
bracket. Then remove old cable from vehicle.
INSTALLATION
(1) Route cable through hole in dash panel. Fully
seat cable grommet into dash panel.
(2) Place the auto transmission manual shift control
lever in "Park" detent (rearmost) position and
rotate prop shaft to ensure transmission is in park.
(3) Connect shift cable to shifter mechanism by
snapping cable retaining ears into shifter bracket
and press cable end fitting onto lever ball stud.
(4) Place the floor shifter lever in park position.
Ensure that the pawl is seated within the confines of
the adjustment gauge clip.
(5) Snap the cable into the transmission bracket so
the retaining ears are engaged and connect cable end
fitting onto the manual control lever ball stud.
(6) Lock shift cable into position by pushing
upward on the adjusting lock button.
(7) Remove and discard the shift cable adjustment
gauge clip from the park gate of the shifter.

easy?

why? got DTC errors? please post them. just curious , me too.
5speed stick, there is no such transmission here. ok JK08 ,usa.
4wd?

mine is 6 speed stick, the 5speed option is the automatic.
6sp is DEH trans.or NSG 370
with NV241 transfer case.
my wild guess is its really a 6 speed manual, with 4wd.
am I correct>?
and is USA, not an Export.
my fsm does not cover, 6 speed VSS, oops.
i wonder if the VSS on the 6peed, uses speed from the ABS.
the automatic vss is on the left side of the tranny case. and input speed and engine rpm speed. but that is A/T.

M/T as your post clearly states is another matter.
the parts list for the 370 box shows no sensors at all ,just 1 reverse switch, then i look at the car 241 transfer case then the parts list.
it too , dont have a sensor. only , 4wd switch and is not a speed sensor.
so that leaves 3 more,
front axle, no.
rear axle ,no (only a lock up switch option)
leaving what, ABS.
must be the genius at JEEP said, one day, well gee abs knows speed, why not just get that for free on all 4speeds.

the A/T needs the sensors to shift right, but not any manual ever.

The electric drawings for jeep jk08 show no speed sensors at all on the M/T. (dedicated to forward speed via the transmission side)

see here a nice JK08 full parts list in PDF.

P0740 JEEP - Torque Converter Clutch Circuit
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
- Vehicle may not shift into the highest gear

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted

When is the code detected?
Torque Converter Clutch (TCC) unlocked for 10 sec., ECM commands converter lock-up and did not record engine speed drop.

P0740 JEEP Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

There is no reservoir...fluid is added right into the tube for the dipstick with a funnel.

Engine Oil


Fig. 1: Be sure to select the proper API quality classification and SAE viscosity grade of engine oil (10W-30)


Oil FIlter (K&N sample)


HP-2004 work for 2.5L and 4.0L


Manual Transmission
The level of lubricant in the transmission should be maintained at the filler hole on all manual transmissions. This hole is on the right side. When you check the level in the transmission, make sure that the vehicle is level so that you get a true reading. When you remove the filler plug, lubricant should run out of the hole. Replace the plug quickly for a minimum loss of lubricant. If lubricant does not run out of the hole when the plug is removed, lubricant should be added until it does. Replace the plug as soon as the lubricant reaches the level of the hole.



Fig. 1: Manual transmission fill and drain hole plugs

DRAIN AND REFILL
Remove the drain plug which is at the bottom of the transmission. Allow all the lubricant to run out before replacing the plug. Replace the case with the correct viscosity oil. All manual transmissions use SAE 75W-90 API quality Grade GL-5 gear lubricant. Tighten the fill hole plug to 27 ft. lbs. (37 Nm).


I hope help you with this (rermember rated this help) Good luck.

Hopefully this will answer your question.

The redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor. The structure was stiffened by PorscheEngineering for sharper steering and lighter weight. The spare tire wasrelocated from the side of the cargo compartment to under the floor togreat relief of owners. The two heavy pushrod V8 engines were replaced by chrysler's first clean sheet V8 since the 60's (SOHC aluminium heads, plastic intake), Chrysler's then-new PowerTech. Although this engine produced less torquethan both previous V8s, it was lighter and got much better fuel economyand provided similar on road performance figures (the 23 gallon fueltank was replaced with one of a 20.5 gallon capacity). The Inline 6engine was also updated in 1999. 10 horsepower (7.5 kW) was added byredesigning the intake manifold. The manual transmission was dropped with this model.
While other Jeep vehicles used the Mopar 5 x 4.5 bolt circle, thiswas the first Jeep following the 1987 Chrysler buyout to receive awider bolt pattern — 5 x 5. The 5 x 5 bolt pattern (also 5 x 127 mm),although common to GM rear wheel drive vehicles and light dutytrucks/vans, has spread beyond its use with GM (and Ford with their 1973 to 1978 LTDs and Lincolns). Chrysler first used the 5 x 5 pattern on full-size half-ton Dodge Ram pickups and Dodge Ramcharger SUVs in 1986.
A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive II.With three viscous clutches, it was one of only a few four wheel drivesystems at the time with triple locking differentals, joining thecontemporary Mercedes Gelandewagen, Mercedes Unimog and Magna SteyrPinzgauer, and the only one of the four with fully automatic operation,although the axle differentials could not be manually locked like inthe other three vehicles.
The 45RFE and 545RFE automatic transmission in the WJ was notable. It included three planetary gearsets rather than the two normally used in a four-speed automatic. Thisgave it six theoretical speeds, and it would have been the firstsix-speed transmission ever produced in volume, but it was programmedto only use five of these ratios. Four were used for upshifts, with adifferent second gear for downshifts. Although five of the six ratioswere used, Chrysler decided to call it a "4-speed automatic". In 2001,the programming was changed to make use of all six ratios. Rather thanhave six forward gears, the transmission was programmed to act as afive-speed with the alternate second gear for downshifts. The RPM at70 miles per hour (110 km/h) on a 545RFE is 2000 rpm, 200 rpm less thanthe 45RFE programming. 1999 and 2000 model year WJ owners can havetheir 45RFE transmission's programming flashed to enable the extra gearas both transmissions are physically the same. The 42RE 4-speedautomatic remained the transmission for the Inline 6 engine. It was notchanged from the previous model Grand Cherokee's.

Yes the clutch is the problem, master and slave should always be replaced together.
