i had taken off my air intake just before the throttle valve to get at the coolant sensors. i noticed a red sheen that made me nervous. i opened the valve and shone my light inside. there is a small puddle of trans fluid deep in there. any ideas on how it got there? is this a bad thing? i know i still have to replace the front pump seal, but i am poorer than dirt. will this impede my ex's performance?

It was sucked in the vacuum line, and it is not a good thing.
 






It means your vacuum modulator on the trans is faulty, likely causing poor shifting. It's not the end of the world but it may cause issue with adding excess carbon to the cylinders and possibly poisoning the catalytic converter and/or the O2 sensor.

The most important thing is to keep the trans topped up, running the trans low is the worst that could happen with the faulty modulator.
 






please tell me the modulator is not tough to replace. i know i still need to replace the front pump sensor, try and get the temp gauge working properly, and get an oil change done. haven't done one in over 16,000 miles. i need to get into some money and get this done. i love my ex too much. i want my fiance to see it has worth.
 






It is fairly easy to do. Did mine a while ago. you will have to pull the front seat(s) so that you can pull up the carpeting. In the middle of the transmission hump you should see an access panel. One you remove the panel you will be able to see the modulator on the passengers side of the transmission.
