Tranny Flush Question

[r_2016]

Hi, my 97 TC has roughly 78,000 miles on it. I was wondering if I should be thinking about getting a tranny flush soon; I have heard that it should be done at about 80K. I have also heard that if there is no trouble with the tranny hard shifting, not to do anything(my tranny shifts ok). Any ideas? Thanks

Well, both are right. I have always lived by the phrase if it aint broke then dont fix it. How ever, 78k is 78k. If your going to do it, I think Steven suggets that you drain the torque converter over a period of time. That way the trans can get use to it. In my case I flush every year and change the filter and gasket adding a bollt of Lucas. I also suggest Lucas for your situation.... Does the fluid look black and worn? Does it smell burnt?

No, it doesnt smell, or look burnt. I was just told that it is a good idea to consider changing the tranny fluid at 80k. I would take it to a shop to have it done; could I add the bottle of lucas after they flush, or should they put it in when they are doing it. Thanks.

Check your owners manual, usually every 30,000 miles the fluid and filter should be replaced, more often if you tow with the vehicle. A good name brand of transmission fluid has all of the necessary additives in it and you shouldn't have to add any.

I am not a big fan of the tranny flush because they do not directly clean-up the pan or filter.
The best service is to actually drain the fluid, remove the pan, clean it up inside and change the filter, and refill with fresh fluid.
I also believe this should be done more often than 80k miles.
