spyder test drive by mechanic caused him to beleive there is a problem inside gearbox on 3rd gear.He stated it was a good idea to get a low kilometer smt transmission and replace the one in car. I have been told hydraulic fluid could cause a lot of problems . to check level you need to reduce pressure to zero in accumulator  by using the diagnostic tester but i do not have one can some one tell me of another way

You can check the fluid by removing the air filter box, it's under neath, open drivers door for pump to pressure hpu and you should see how much you have.
Pump should go for 10-20seconds. Any issues with it, the smt light would display a code anyways.
