P0734 is a gear ratio code for 4th gear. In other words TCM sees 4th gear is slipping. P1529? I don't know I'm on my cell phone.

Sorry to tell you that it is incorrect gear ratio codes. Must replace the transmission.

p0734- Gear 4 incorrect ratio
p0732- Gear 2 incorrect ratio

Unless you have recently had your transmission replaced with a junkyard unit you are having a problem with the transmission control computer.

Good Luck!

Code 0734 : Gear 4 Incorrect Ratio. you may wanna take back to the Mechanic and tell him whats going on and let him deal with that. Good luck

Sounds like a dirty of faulty speed sensor. They can be removed and cleaned. Better off replacing. Do check the wires to the speed sensor. Trace wires from tranny to instrument cluster and make sure they are all in tact and clean.

Hi

Well two of the tranny codes ; P0734 and PO732 indicate gear 2,3,4 ratio incorrect. This can be caused by poor readings at the input and output speed sensors or pulse generators. The P1709 code is in reference to the kickdown servo switch.

Replacing the pulse generator set and TCM reprogramming( as per TSB) may solve your problem, otherwise you have a major component failure in the transmission unit. I would get some line pressures at the transmission checked first.

Sounds like the transmission is in fail safe mode, this happens when there is a transmission fault, you only have two gears 2nd and reverse.

Hope this helps - Steve

hyundai accent codes p1529 and po734

P0734 - 4th gear incorrect ratio. P1529 Malfunction Indicator Lamp Request. Problem is in the transmission.
Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

P1529 means nothing more than the TCM (transmission control module) has requested that the ECM (engine control module) turn on the check engine lamp.
P0734 basically indicates that your transmission is slipping.
You need to take this car to an authorized repair center for hyundai cars. Replacing the filter and fluid on the transmission might save this transmission but I would be willing to bet that a total transmission rebuild is in order.

Good Luck
