1988 4runner 3VZ auto tranny 3in body 4in SUS 35's and stock gears. Receanly had engine overhauled and the problem started afterwards. Took it to a local shop and they replaced all the seals an wearable parts. still leaks. any suggestions? I am still not sure whether it is oil from the rebuild or tranny fluid. I know there is a color diff. but being color blind kind of kills that. I noticed someone posted a thread about there oil cooler leaking. where is that located?
