ok.... my car leaks massive anitfreeze and i dont know where from last night the "bird cage" light came on so i filled the overflow can 3/4 full ... i went out to start my car today and it wasnt going to start over but it ended up going... and as i drove away i noticed a puddle... so i pulled over and looked in the can ... everything seemed find little less then i put in but figured it just went tot he tranny... but then ... i drove around today for about... 30-45 mins and came home... checked my bottle... there was fluid leaked under the overflow can and i opened it and it was filled the the brim... was no signs of oil atall... also... when i started driving today my rpm's would shoot up to 5-5 1/2 until i stopped at the light and then it drove at its normal 2-2 1/2 i drive a 89 auto turbo... and i have 1 last question... why does my car shift at 3-3 1/2 when im giving it full throttle... is it suppost to? ... seems kinda low dont it? considering the redline is 6 1/2?....please help
