Went to the Dealership this morning. Had them do a full flush with T-IV and they inspected the tranny. I explained the situation to the mechanic and he test drove my celica. He said there was no damage as he could tell and that I should keep an eye on it. I drove home and let me tell you there was a HUGE difference. I can't even feel it shift. With the Maxlife, the tranny felt sluggish and you really felt each gear pop in and out. With the T-IV ATF it drives like new. I am here to say that whatever claims the back of the Maxlife bottle make or the Valvoline dealer make, or 1-800-TEAM-VAL MAKE it is NOT the same and I will NEVER EVER trust that product in my car again. For 30K miles I thought my car had an engine problem or my muffler had a leak it was so loud, I kept having shops tell me there was nothing wrong. Today, after having T-IV AFT flushed the car drives like new and the noise problem is GONE!! AMAZING how that works. All that headache and hassle to save a few bucks. Mt tranny service cost 114.00 at the dealer and the recomended interval is 30K. miles. That is about once a year. I am going to just set aside $20. at each oil change for the service so annually I will have the funds to get it done. DON'T trust Valvoline MAXLIFE in a celica!! Rough sounding ride, rough shifting .......can't be good.
