I have a 2004 Tbird and want to either add the small bottle of additive to the transmission. Can't seem to find any information on how to add the fluid.

So now I want to drain and refill transmission with fresh ATF. What is everyone using? MerconV. Should the old "wrong" fluid put in by Ford at the factory, be flushed out?

Thanks Raymond,It is your call, but it doesn't seem to be necessary per the manual
Thunderbird Manual- Normal maintenance - Fluid change not necessary, filled for life .
Severe duty maintenance - Change the fluid at 48,000 miles intervals

The links are already in all your posts above- https://forums.fordthunderbirdforum...smission-and-power-steering-fluid-xl-3.10189/Thanks Raymond,
The transmission still has the crap fluid Ford put in it when new. I want to put the proper fluid in. It was a recall notice. I only have a little over 8,000 miles on it, and never a problem with shifting, but don't mind heading off a future problem now.
So, is this the best to use?
