ok so the car is leaking fluid from where the flywheel is so i think its the rear main seal.now my question it is where is the rear main seal located?and is the crankshaft seal the same as the rear main seal.If not then how could i tell wich one is bad with out pulling the tranny out ?please help.....

First what color is the fluid? if it is red then it is trans fluid, if it is brown or black then oil..... if it is oil then yes it could be the rear main seal or oil pan gasket..... if it is red then it could be the torque converter leaking, or trans pan gasket leaking, het under there and check it out....

well you stated that it is leaking from where the flywheel is so in this i assume that your car is a manual/standard transmission cause a flex-plate is for a automatic transmission so between your exhaust and your trans there is a debris cover with 3 10mm bolts remove those if you would like to see into the bell-housing letting you tell which side of the flywheel the fluid is running down if it runs down the engine side its the rear main seal/crankshaft seal if its on the trans side its the input shaft seal. if it is a automatic it would be easier to tell because of the read trans fluid but the manual trans has either 10w-40 or 10w-30 engine oil in it and would look the same as your engine oil good luck hope this helps

1990 Acura?Replace them both along with clutch assembly, pilot bearing and throw out bearing,Eliminate these problems all at once and you won't have to wonder anymore.Look at it this way, you have to fix the problem which mean you'll be taking the trans out and with that you have access to the clutch, flywheel and rear main seal, if your not sure about the integrity of the parts replace them Now and you won't have to wonder about it later.If it is an automatic you need to replace both the rear main on the engine and the input shaft seal on the transmission and consider a new torque converter and completely draining the old fluid from the trans replace the filter and fluid at this time too. Then you know what has been done and what you've got plus you learn some things in the process.Learn by doing Thanks Bill B
