I screwed up, now what?
Well I screwed up.
On my recently purchased 2004 tundra I was checking the fluids and noticed my automatic transmission was low on fluid.
Last week without hesitating I went to AutoZone and got some ATF fluid which at the time I thought was correct. I didn't have a Haynes manual which was the first mistake.
What I purchased was Castrol transmax DEX/MERC.
I added a little over 1.25 qts.
Yesterday after reading through some stuff in my newly purchased Haynes manual, I found out that I should've put Toyota type IV ATF fluid in.
I've driven about 350 miles since I put the wrong fluid in.
Do I go to the dealer and have them do a complete flush and them refill with brand-new Toyota recommended fluid?
I know my local dealer does what they call a fluid exchange? But I don't know exactly what that completely covers.
I do have a mityvac that I have used to drain oil on my previous vehicles, I simply stick a tube down the dipstick and pump it and the suction pulls most of the fluid out.
Has anyone else admitted to doing this, and what did you do?
I know without completely draining /flushing all the fluid, including the torque converter there's gonna be some of this new fluid in there.
