Looking for a reputable shop that will flush my trans an fill with new fluid.

It isnt giving me problems or anything but the fluid is black and i dont know when it was last changed if ever i bought the truck with 160k on it. Now has 200k+

Went to dealership an they told me if it aint giving me problems than to not worry bout it that it could possibly start having issues after the flush.

Whats yalls opinion on this

And if yall think it needs to be changed whats a recommended shop in the houston Galveston area

You don't flush an Allison. Just drain the pan and refill.

Care to elaborate? We do it all the time.. Have a flush machine that hooks up in line of the trans lines and uses trans pressure to exchange fluid.
