Well I am goin to attempt to fire up this 1990 TGP I purchased this winter and see what it needs. When I purchased the car the radiator was unhooked. Today I went to install the radiator and could not find the oil line to plug into it. I then looked at the radiator and the was a plug threaded in the oil line fitting. Is there some kind of bypass that was done on the car? I see a few hose clamps and hose right behind the oil filter and I am thinking thats where it was bypassed from but cant understand why. Thanks guys

Not quite certain what you are talking about?  The radiator has a trans cooler built in, and these cars have an aux trans cooler as well.  There is an oil cooler sandwich piece on the oil filter, but that is connected through the heater hoses and such.

Pictures would help, so we know exactly which area/hose you're talking about.
