Please car gurus in the house, my car(maxima 2000) usually looses power after about 20minutes drive especially in hold-up. I mean it will refuse to select gear until I off the engine and restart. Though, after restarting, it will be selecting fine for the rest of the journey.
I have changed the gear oil, top it, changed air filter still no solution.
Please good people of car section help me out, what do I do to salvage the situation. Thanks for ur quick/usual response, God bless.
