Might be really simple - but EXPENSIVE! I had a similar fault - apparently the first planet set breaks up. Cure - a new box. Price - crippling!

Don't be tempted to skimp on the box. Get a rebuild from a reputable supplier. A s/h box will set you back around £5-600 in UK where a rebuilt (guaranteed) will be more like £1800. The thing with the cheap box is it costs about the same to fit but you don't know how good it is till it's too late! Then you're still shopping for another but you're £600 lighter!

Also, you could be buying other faults. If the speed sensor has had a problem - the box will change badly (snatching) and that will be another £250 where the expensive box will have ahad one fitted!

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.

https://suzukipitstopplus.com/Products/1064-2005-forenza-reno-service-manual.aspx

$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.
but takes a real ASE MECH, NOT AFRAID TO DO ALL FSM CHECKS ON CAR. FACT.


fsm quote

Trouble Code: P0734 (2.0L L4 VIN - Auto)

code p1750 refers to AT-hydraulic system mechanical malfunction====causes --wiring---shift solenoids--ECM---transmission mechanical fault. Have a pressure test done to determine if there is a mechanical failure in the transmission.

P1750 code


P1750 Electronic gear selector module. Low control unit supply voltage too low.


Clear this fault first, as gear position sensor is not saying transmission is in P or N in order for engine to start. Check voltage at battery. Should be 12.65 if fully charged.

Low voltage causes false codes too and if too many set they will need clearing. Spilling tea coffee or soda down the shift gate can cause similar problems. Also the wiring to the transmission can become oil soaked and not pass full voltage to shift module at the connector.
It is also possible this code has nothing to do with a no start and you have another componet failure. .

Transmission selonoid assambly


Diagnostic Test Code (DTC) P1750 is a "generic" OBD fault code that is output by your engine control computer to let you know that the transmission control computer is reporting a problem with one of the transmission control solenoids. To find out the nature of the problem and which of the solenoids has the failure, you must access your transmission control module and retrieve the fault codes from there.

The transmission control computer outputs 2-digit codes that are not accessible by a generic OBD code reader.

Have a transmission code P1750 on 1998 Mitsi Ecplise Spyder GS . I had the transmission rebuilt about a year ago,the check engine light came on and I had it diagnosed .The mechanic checked it out and said...


p1750 is a Manufacturer Control Transmission. i work at advance auto parts and we get these codes in from time to time. what i tell people is alot of times it is infact your solenoid box assemble is going. what that does is to tell your transmission when to shift into gears. im assuming your car is having a hard time shifting gears. to replace that part your looking to spend about 200 to 500 with parts and labor. unless you want to do the job yourself. than if im right it should run you between 150 to 200 for the part.

DTC P1750: Mechanical Problem in Hydraulic Control System of A/T Clutch Pressure Control Solenoid Valve Assemblies A and B, or Problem in Hydraulic Control System

NOTE:
• Record all freeze data and review General Troubleshooting Information before you troubleshoot.
• Keep these replacement solenoid valves on hand:
• A/T clutch pressure control solenoid valves A and B
1. Check whether the OBD II scan tool indicates another code. Does the OBD II scan tool indicate another code? YES - Perform the troubleshooting flowchart for the indicated code(s). Recheck for code P1750 after troubleshooting. NO - Go to step 2.
2. Turn the ignition switch OFF.
3. Replace the A/T clutch pressure control solenoid valves A and B.
4. Reset the PCM memory with the PGM Tester or by removing the BACK UP fuse in the passenger's underdash fuse/relay box for more than 10 seconds .
5. Drive the vehicle for several minutes in 1st, 2nd, 3rd, 4th, and 5th gears in the position.

Code p1750


P1750 Solenoid Assembly Malfunction. The TCU is sending a fail signal to the ECU.
It's more like a transmission problem. Bad solenoid in the transmission.
