My 2007 Hyundai Elantra sometimes while at say 45 or 65mph cannot rev beyond 2500rpm. If I come to complete stop and restart the car, the issue goes away. At 106k miles, I got transmission flush done per the manual (105k). Then car behaved slightly better and one-day, the issue recurred and check engine light came on with codes P0700 and P0743 informing that transmission solenoid may be erratic and as a fail-safe, the car shifts to D3. There is a manufacturer Technical Service Bulletin (TSB) 10-AT-010 on it saying that 46313-23000 needs replaced. Questions:
- I have a nice Aamco guy who will drive the car around with scanner attached hoping to catch the issue. If the issue is confirmed, then I will get the job done. Yelp will reduce the cost $675 by $50. Any other coupons available?
- Has someone else had similar problem? I don’t want to replace solenoid and then find out that a transmission rebuild is needed. Guidance is appreciated.
- I have a mechanic who will do the job for $200+part (~$250). Since the issue is related to transmission, I am thinking of going with Aamco by giving up on ~$175 savings. Right call?
- Once solenoid is replaced; how much life would one expect based on prior data i.e. consumer reports etc? If they fail every $100k, should I mark my car for sale after putting say 50k more miles on it and steer clear of Hyundais / Kias in future?
