Question about 2002 Hyundai Accent

1 Answer

First problem P0734, then some internal failure, now 3rd tranny

2005 Accent
Original tranny had code P0734, they replaced. Then next tranny they said had some internal failure so they replaced it. The third tranny is doing the same as the second. Problem is an intermittent RPM surge between 65 -72mph. The 2nd tranny never threw a code nor does the current but the problem exists and until I can get a mech to eye witness the problem (surge) they can't do anything. I only have 23000 miles left on my warranty.........suggestions???

Take it back to the dealer and have them test the TPS. The PCM takes information from the TPS to control the transmission fluid pressure that controls the firmness of the shifts and the amount of fluid pressure to hole the gears in place. The reading from the TPS should be smooth and constant. it the TPS passed then it's a good chance that your looking at another transmission. P0734 mean's the 4th gears are slipping. Good luck and hope this helps. Keep me posted, be glad to help.

most P0734 codes are due to misshifts in the auto tranny. Most often due to a faulty PCM, ECM, TCM or internal blockage, 4th gear is not engaging correctly

P0734


Description of fault code P0734:

This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by the 4th gear ratio, while the transaxle is engaged in 4th gear. This malfunction is mainly caused by mechanical troubles such as control valve sticking or solenoid valve malfuctioning rather than an electrical issue.

From experience (sorry) you will end up replacing the transmission. This code usually indicates an internal mechanical failure.

I have had the transmission rebuilt in my 2002 Hyundai Accent GL only 8 weeks ago and I have gotten the codes P0734 and P1529 now. So does that mean my mechanic did not do his job?


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

2002 hyundai accent.transmission works great if you leave it in second gear.if leaving the selector in drive the transmission will start out in second and never shift to overdrive.when coming to a stop in...


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

I have two codes showing on my daughters 2002 hyundai, P1529 and P0734. What should I look for to repair these problems


po 734 is transmission code, unfortunatly its not good, an internal failure, probably a kickdown servo failure,hyundai offers a reman trans, with a good warranty i would look into that, also they will give you a better diag and options on what you have, however if you are the original owner, and have proof of proper maintainance,the trans may be covered on the 10 year 100,000 mile power train warranty

There are some sensors on the transmission that tend to go bad. You may also need to check the wiring. Could be a computer problem. How many miles?

seems to me , the 3rd gear shift range is slipping.
You probably have internal failure.
You should take to transmission shop
