[QUOTE="machoheadgames, post: 432162, member: 18789"] just to make sure - it is leaking motor oil and not trans fluid, correct? Since the PCM has to have the function for the torque converter lockup built in, and that PCM wasn’t available until 1994, I’m wondering what is controlling that trans. Anything from 1993 would be for a manual and would not be providing the TC lockup function. That trans almost guaranteed has to be from a 1994 or later due to the odd bellhousing pattern to bolt it to a 2.5 which was not available until again, 1994. If it’s a 1994 trans, then it would have the lockup converter on it. If the lockup converter is not being activated by the computer, then the converter could go bad from overheating. Basically where I’m going with this is trying to rule out a bad converter leaking from not being operated properly. Obviously you can usually tell motor oil vs ATF, but something to make sure of nonetheless. [/QUOTE]
