1993 Camry LE, 260K so far on the transmission and runs good. It does jerk a bit when shifting gears.

I'm insane about cahnging transmission fluid every 30K or so..

But with the age of the transmission with as many miles as it has, what is everyone's experience in the best additive to add into the next transmission fluid change to keep it lasting as long as possible?

Lucas?

any others come to mind??

 

In my opinion your best bet is to continue changing the fluid every 30K, by doing so you are far ahead of most owners. Dirty and worn out trans fluid is the No 1 cause of trans failure.

Make sure the car is fully stopped before changing trans gear directions. Shifting from one direction to the other when still moving (no matter how slow) will cause future trans problems.

Remember to change the diff fluid.
