97 Ts Se 3.8

[99MBSport]

While driving back from Conn. today I noticed that my Tach was reading 3000 at 70MPH and it seemed a bit high to me, so I pulled over and checked the Tranny fluid.
Well it took 2 pints of fluid to bring it to the full mark and all seemed well for about 50 miles or so when I noticed that the same thing was happening again. Can the Vacuum modulator cause this to happen or is it the TCC Lock up in the valve body? I hate to start tearing this apart and do a half arse job. Van has 132K and has had a good history of service by the prior owner. Thanks for any help. Also How easy 1-10 is it to replace the TCC if I need to. Can it be done in a day?? Thanks

I guess it´s a '95 3.8?

First thing to do is to read the codes! If the TCC disables for some reason, there is at least one code assosiated with this. This code will not illuminate the CEL, but still be waiting in the memory to be read.

I have a 95 trans. 3.8L that lost trans fluid through the vacuum modulator.
You will see it when you remove the vacuum line from the modulator if it is faulty...KEV
