i replaced my 91 camaro 700r tranny with a 700r from a 90's model truck i had to swap tail housing and gears from the shaft. i also replaced the front seal. i filled it up with fluid andtest drove it everything was fine when i parked the car with the engine running tranny fluid started running out like a water fall. i jacked the car back up to make sure the lines were tight and to see were the leak was coming from i could not tell. i started the car while it was jacked up and nothing happened i let it run for about 30 minutes and no problem, i let teh car down and test drove it noticed smoke coming from under d car i parked the car and look under it there was a small leak no big deal i thought i turned the car off and just like before fluid coming out like a water fall.. any suggestions would be appreciated
