Drivetrain Tranny fluid

[DemonGT]

How often should the tranny fluid be changed in a Tremec TKO. Put it in the car ten years ago and only have a few hundred miles on it.

It's probably ok. I was in the same boat with only 1k miles on my t5s fluid in 10-11 years.

Heat is what deteriorates trans fluid, and manuals tend to run cooler anyway. What ultimately convinced me to change it was condensation given there is a vent. Probabky wasn't necessary, but the fluid looked brand new when it came out.

a shower thought....if the tranny is new and i put fluid into the tranny as the directions stated was i suppose to add more fluid
after driving the car?

Should not need to if filled correctly when installed. Just check it to make sure though.
