Trying to solve a small leak issue on my trans. At first glance I thought it was simply the trans pan gasket leaking. Cleaned up the area, replaced the gasket... still leaking. I think it may be coming from the round servo plate on the passenger side of the trans under the lines? Is this a common leak spot? I was looking into an upgrade that changes that produces a more positive shift between 1st and 2nd. Product is made by TCS. Is this a good idea with a trans that as far as I know has not been rebuilt?
I may get yelled at for this next question but here goes.... I was informed by a Ford mechanic ( old schooler) that running Merc 5 in these trans works really well. I have been running it for the last couple summers, everything seems good, shifts well and there where no real signs of badness in the pan... Is Merc 5 fluid too thin for this trans?
