Where is the fuse for the tranny it takes off in 3 gear it is a 4 speed auto i blow a fuse or some thing thank you bob

so did not check all fuses first?
then scan the PCM for all transmission DTC errors first?
oops.
1999 dodge durango 5.9L (46RE TRANS i GUESS)
there is no , in or on tranny input speed sensor
the PCM uses ENGINE RPM for that. (crank sensor RPM, CKP)
if you scan the PCM you will not see DCT error for input speed sensor there is none.

Trouble Code: P0753 (5.9L V8 VIN Z Auto)
A/T 3-4 Solenoid/Transmission Relay Circuit Failurenone there below. but sure CKP is. crank speed
and SOL 2 and gov pressure, are key.

SOLENOID 2 bad? above.
why are you not scanning it first. for DTCs
what if governor pressure signals are wrong. pin 29
what if the scan told you it was. likethis.
examples
Trouble Code: P0700 (5.9L V8 VIN Z Auto)
Automatic Transmission Control System Malfunction
Trouble Code: P0711 (5.9L V8 VIN Z Auto)
A/T Transmission Fluid Temperature Sensor Signal - No Rise After StartupTrouble Code: P0705 (5.9L V8 VIN Z Auto)
A/T Check Shifter Signal Circuit Malfunction''
Trouble Code: P0715 (5.9L V8 VIN Z Auto)
A/T Input Speed Sensor Circuit MalfunctionISS is what? (CKP is my guess)

lots more on gear errors
then
Trouble Code: P0748 (5.9L V8 VIN Z Auto)
A/T Governor Pressure Solenoid/Transmission Relay Fault783 is last one. lots of P07 errors on this box
all covered in the service manual in detail.
learn that some cars the PCM has what are called virtual or derived sensors, like engine load is (used to shift too)
and inputs speed, is CKP sensor and ABS the 4 sensors abs are averaged to do speed.(mph)
but in this case it is crank speed CKP
no PCM schematic shows any ISS at all

one can not fix modern cars lacking a SCAN tool, USA OBD2 .
not really and ASE class Day 1,
read all TSBcheck all fusesscan it.service manual online, great !

the RE is electric shifted the older RH is hydramatic, shifted and not the same thing,so how can if fail.
sure speed sensors sure.but what else.
the pcm fails to pick he 3rd gear soleniodthe PCM is in limp mode.the gov signal sensor is bad. and wrong (not sure how to replace it me., output sensor dead. (no)PCM sees gross CKP errors crank RPM way off or skips.low pump pressure in the transservo drive to band failing and no 3rd gear. possible.more simply after scan replace this set kit.https://www.ebay.com/itm/194076774950?hash=item2d2fe09226:g:flYAAOSwX9FZKCwl&amdata=enc%3AAQAHAAAA8Auj9VxgzbBbY1y72FuSN8kY5Rr6S3No4BqIm0Ahxvpol8ifEkPhCjcL9RfwxI1dPT9gboPhrqEcTmFagdyeF9TiffbFSjrtI7XOnIbc8G%2F6JCafmPc6idA7aFhq5Y%2FTxfPDpQyhD1vs1akPE%2FD%2FoH3e9fD3d%2BwcwGu4N0GMG1fIDbLPAnG6cWwwzGUd9zPVWm9tFxHxI1viGJn2aLG7%2F3zQjo4VHwpnCeea9lwjV18DOhcloDRRJMzBojw3Hfb8xJdJUJb2cwSgy1LKickqaxU8QdQHy2zv8NBG1ACbb3ZN%2FE9bD%2FlT1cBqykbdirlNlA%3D%3D%7Ctkp%3ABk9SR4SKlvbYYA

One (1) New Borg Warner Pressure Solenoid(EPC)
One (1) New Governor Pressure Sensor (Transducer)
One (1) New Overdrive & Lock-up Solenoid Assembly & Harness
One (1) New Governor Solenoid Body Gasket


recap and conclusions. electronic shifted trans. TCM
not getting 3rd gear has many causes:
I'd hazard a guess that pump output pressure and regulator are working in the box. (1 >>2shifts ok)
3rd gear solenoid not dead?
and the lies told by governor pressure sensor, makes the TCM shift wrong (computer GiGo logic) caused.
3rd gear servo piston dead.
or some odd Limphome mode, (iDK them all) (ignoring DTC errors? ) Some trans in limp slip a gear.
The governor must see tail shaft speeds correctly or it will not up-shift all the way.

a scan tool can be bought or rented. or ask others to scan it, any shop can, or some Autostores can
there is no reason no to scan it after fuses check, unless 3 gear is needed to get there (hummmmmmm)
$100
also the tool pays for it self (it's free man) the first $100 in labor not spent,. amazing facts no?
a real scan tool not $20 lame code reads,
a real tool see all Dodge codes.
cheaper readers only show DTC errors only with "CEL lamp ON"< , P07xxx code (7 means transmissions errors)
better tools start at %100

the fuse that runs pin 16 on the OBD2 DLC scan port (12vdc ) must not be blown or the scantool fails (not broken fails to communicate)

TCC locks at high speeds. where is yours failing, how fast.?

so at what speed, do you expect TCC lockup.?
unless you have tranny slip.. a whole other problem in any gear.

this old tranny has, pure mechanical ops. no TCM here.
most old tranny have the foolwing inputs.
1: driver right foot called the TV cable or detent or passing gear cable.
it can stick and cause late shifting
2: Tail shaft speed, this is the tail speed governor that shifts by speed.
3: the load vacuum modulator that shifts by engine load (vacuum)
4:gear lever positions PRNDL.

the 5th input is the TCC relay that the ECU controls
the ECU activates it under inputs of RPM and MPH (VSS1)
so if the relay closes at the right speed, then the ECU and relay
are working, if the TCC lock up is delayed, then the TCC internal
solenoid is bad, leaks or the acutal lockup is bad or pump pressure
is too low, or any leaks from the solenoid to the locker slave.

with auto tranny, when you relieve the acc pressure on the tranny it will drop into a higher gear, this is normal but if your road speed is low and you put your foot down hard it may change back 3 gears, it decides what gear it requires in relation accelerator pressure and road speed, the tranny does have a switch near the selector, this lets every thing know what you want it to do, this is adjustable but can fail also

Well yes the obvious answer is something electrical is blowing the fuse.
First question is, which fuse ??

What kind of problem do you have? If it is a 4 cylinder caravan, they usually have a 3 speed auto that doesn't have any shift solenoids. If it does have the 4 speed auto, the shift solenoids are on the front of the transmission case.

tranny is good,rear dif gears are for an auto tranny.put lower gears in it.

check fluid if burnt or brownish change filter if it hasnt been changed may be problem -- no external adjustments on tranny to replace a band-valve body- gear -clutches have to tear down trans

The only thing that you can do is check the trans fluid.Start car,run it through all gears and end in neutral.Handbrake on.Now check the trans fluid level.Make sure engine is warm.If needed add fluid.If this is not the problem,a tranny expert is the go.There is not a lot anyone can do with an auto trans at home.Hope this helps

ck the condition of the tranny fluid. If the fluid is very dark, it will need changing. Another problem with the jeep auto tranny is that if the fluid has not been changed in a long time, the clutch material will wear and clog the tranny filter inside the pan.If there is alot of clutch material in the pan and you change the fluid and filter, sometimes the tranny won't work because the clutches are worn out too much.

It sounds like the tranny is over heating, you might want to have the tranny check by a pro. Way to complex to work on with out experience and training.
