May be the filter . this is what filters the tranny fluid . and if clogged or dirty will prevent fluid travel thus giving you slippage . can be bought at auto part store and put on your self in under an hour. if it started sliping and slowly got worse then it very well could be. now if you dont stop driving it you can blow it up.

2005 suzuki reno code po734

lots! (can talk this all day) (a/t are no simple)
find a smarter shop!
going to a transmission shop they go , gee, that is all we know
here, swaps (or rebuilds only) AAMCO?
first stop is:
try a real ASE mechanic that can do the many tests on car.
called ON CAR tests, in the FSM
all my answers are for usa, cars,if not ignore all my posts.

$4 and is ReAL, not fake or cloned'

goggle find my ASE shop, BINGO.
type zip bingo2.

700 means tranny errors, any. (ignore
734 ( serious)
check levels yet, per above method(link?) step by step?
check fuses just in case.
oddly this car has a separate TCM tranny brain,
that drives 6 solenoids inside the box.
most suzuki a/t there is a secret( in fsm on all that do)
manual test mode. on most you un plug TCM connector and drive
to see if 4th gear really does slip, my guess is yes.
if yes slips, its bad trans, of no slip bad solenoid.
watch out manual mode can skip gears, #2 or 3, so test only 4.

replace the valve body, we do on regular trans, not sure
if that works on this transaxle type? (i dont have the book on this box)
in my shop i can hot wire solenoid(before retired)
this proves not TCM and is in the box
then i check solenoid coil ohms. 10 ok , 0 bad infinity bad.
10 can be 20 , idont know, the book above tells coil spec.
the soleniods can be bench tested.

Trouble Code: P0734 (2.0L L4 VIN - Auto)
4thGearr Incorrect Ratio (or slips)

Number of Trips to Set Code: 1

Trouble Code Conditions:
TCM detects any inconsistency in the actual gear ratio.

Possible Causes:

Input clutch solenoid valve

Front brake solenoid valve

Direct clutch solenoid valve

High and low reverse clutch solenoid valve

Each clutch

Hydraulic control circuit

Check Engine Light P0740. Car stalls when starting (occasionally), and the transmission slips when stopped.

This code is set when the transmission control module detects improper voltage at the torque converter clutch. This can be caused by low tranny fluid/dirty tranny fluid/defective torque converter clutch solenoid/electrical connections to from solenoid

A/T tranny issues. (solenoid )
my auto tranny is slipping in call gears. forward and reverse?
there are no guessing, just tests.
check all fuses.
check AFT levels using the operators guide, (dont guess at ways, do it right way, as 99% dont)
so DRIVE is stuck in 1st gear, or 2nd?
the connect the jumper for the TCM, and get the flash codes.
if it says VSS is dead, then it is.
why wonder this. the TCm will not lie, it will see any bad VSS signals and report them on all cars made. but has flash codes this year.
there are 3 or 4 paths here

1; inputs to TCM wrong, sure it will shift wrong. how could it not.
2: TCM bad , it has good inputs and its outputs are wrong.
3: the TCM to tranny connections are bad, (corrosion)
4: the Solenoids have the correct inputs but fail to work.
bad solenoids or far far worse.
note the order here.. only this works unless guessing with $1500 fist of dollars is ok.

the FSM covers each tests. from 1 to 4.
for on car tests. if the solenoid tests pass its a bad tranny.

I have 1998 volkswagon jetta with the check engine code P0758

P0758 Volkswagen - Shift Solenoid 'B' Electrical

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 'B' valve
- Shift solenoid 'B' valve harness or connectors
- Shift solenoid 'B' valve circuit is open or shorted

Worst possible scenario is that the Transmission Control Module has noticed the solenoid is either taking too much current (a short circuit) or too little current (an open circuit). The problem could be in a few different places: wiring between the TCM and the tranny, wiring internal to the tranny, the TCM has gone bad, or the solenoid itself. You can narrow this down by checking the resistance of the solenoid coils at the TCM connector, then at the tranny connector on the tranny.
Good luck, the mark 3 transmission is notoriously finicky.

2000 dodge caravan will not shift out of 1st gear

Actually it's stuck in second gear. That trans is an A-604 ultradrive and when the sensors read a problem it will put it second gear rather than letting it slip. This is great if you're in the desert and need to get home but it sucks if you're on the highway and trying to keep up with everyone so you don't get run over. From here though you need to go to a transmission shop that has a scan tool and can see what the tranny is doing electronically. Sometimes a bad sensor, solenoids or wiring. Sometimes the sensor is actually reading that the tranny is slipping and needs repair. Bad sensors and solenoid pack are common through those years. I hope this helps.

Voyager transmission problem

Sounds like you need a solenoid pack to start, and possibly a service. If the tranny is not slipping, the solenoid pack is stuck and not tell it to shift up. Could possibly be a TCM, but not as likely.

Transmission Slippage

You can have the clutch and the pressure plate checked. If it is an automatic tranny you may try to drain the fluid and have it replaced or have the solenoid cleaned out or checked. The solenoid controls the hydraulic pressure to the clutch

Tranny slips & wont shift past 2nd gear

Ok, you will need to first check the fluid level in this transmission. if the trans is sealed, you will need to take to the dealer for a fluid check. assuming that the fluid level is proper, this will usually be caused by a faulty transmission control module and faulty shift solenoids as well. these devices are located on and inside the trans and i recommend testing each device for flaws.

Most slips are the result of gear ware but, the solenoids and TCM will cuse this issue as well.

Slips between gears.

well I guess I will say change the fluid again and change the filter- you simply do not have enough miles to be transmission failure- so my guess wil be the shift solenoid as well - contact dealer to confirm.They will have to change with solenoid anyway.I sold my last honda with 275,000 miles and it had a hard life- no issues ever
