I went to a Valvoline service stop-I know better and won’t do it again- for a quick oil change. They offered me a transmission fluid as I was near 60K and it is required maintenance to maintain my warranty. I went ahead and did it. Sadly, I don’t know my car well and when it started to shudder, I didn’t immediately realize it was an issue. I went back after 3 weeks, had them check levels, and they topped them off. Problems still happening so I went to the dealer. They tell me the transmission needs to be rebuilt, and it isn’t covered under warranty. They suggest I go after Valvoline to cover the repair. my husband has been trying to argue our case with them. Question for the board. Valvoline states their MaxLife Fluid exceeds the recommendations for my ATF +4 transmission loving vehicle. We managed to get the specs for both fluids, and they don’t match. anyone know which numbers matter? For example the ATF+4 Viscosity at 100C cSt is 7.55 typically, and @40C cSt it is 34.13. MAx Life is 6.11 and 28.18 for those same levels. The index is 198 and 173. What do those numbers mean, and how can I argue my case. The dealership says they can’t prove it was the fluid, but the car was FINE before I went in, and not afterwards. It also shot out a overheating Transmission error when I brought it in.
Any advice would be wonderful, but please be kind. I know I made a dumb mistake going there, and I won’t go back. I was trying to do the right thing and could not reach my hubby on the phone that morning to get his approval so I made the call to go ahead and do it when the guy suggested it, I just wanted to get my oil done since I was overdue for that. I feel sick over this whole issue.
Thanks to all responders!
