trans

i have almost 100,00 miles, never had transmission fluid changed on a 12 tundra (sealed).

dealer says they will flush, im confused, some say not to flush, on first change, but, one dealer dont touch the trans, and the other, only flush, any help? thnx

 

Drain and fill, repeat every couple thousand miles.

 

Don't have flushed. Toilets are flushed. Have or do a drain and fill. Roughly 3-4 quarts. As mentioned do again in a few thousand miles, maybe depending on how the fluid drain the 1st time looked. Important to measure and replace with same amount.

 

I went to my local dealer to learn what they did for their transmission service. It was some kind of power flush and they described a level check outside the factory service parameters. I walked away with no confidence and did it myself. Bought the various tools, the scan tool app to monitor pan temp, 24 qts Toyota WS fluid, and did a step by step service. Now it's right and I can do it whenever I want for the cost of fluid.
