My 93' 500 SEL with 85K had been at the repair shop for about two weeks having the timing chain and guides replaced. Went to pick it up today and they told me the front pump on the transmission was leaking. They showed me. Leaking bad! My question is, the car was sitting for two weeks as they were replacing the timing chain, etc. What would cause it to start leaking all of a sudden? The mechanic told me that during his test drive while running the car hard after stopping he noticed the leak. Please tell me what is going on here. HELP! Now he is saying another $1,000-$1,500 to soft rebuild the transmission.

HELP!!!
