SOURCE: 1998 pontiac transport 3.4 auto leaking trans fluid

It sounds like the Transmission line has a leak. Check the transmission line from the transmission to the radiator. You have two steel lines which runs to and from the transmission to the transmission cooler in the radiator. The line could be corroded and may need to be replaced, good luck and service the transmission too. The transmission on the transport are know to have problems when ran low on fluid or dirty transmission filter.
Good luck and hope this helps.

SOURCE: I need to drain and flush the cooling system on my car the

the van will be okay just dont fill cooling system with water and leave it then it will freeze the motor. also you might freeze its not an easy job, is the core leaking, or are you not getting heat, if its no heat then just flush the core with waterhose from hoses going to it, just remove the hoses to core and use waterhose to flush out, go into both hoses one at a time do this a few times and you will have heat. if its leaking then replace it.hope this helps.

Testimonial: "Thanks yes the whole system needs flushed and the core needs replaced took me about 7 hours yesterday to get the core cover off. I to work today froze"

replace the shift solenoid for the 3rd gear

Testimonial: "gave me a good area to check on a problem and will probably save me a bit when it comes to mechanic not have to guess for ever"

SOURCE: Unable to shift any gears (manual trans)

Have someone watch the clutch arm when pushing on the clutch to make sure it is actually moving when the pedal is pressed. Fiero's are miserable to get the clutch bled properly
