leaking transmission fluid from the front, what causes that? The small hoses connect to the cooling fan are saturated
when you first get on highway it runs good at 60 or 65 mph. about ten minutes when engine reaches full warmth
the car starts losing speed and won't go past 50 with the gas pedal almost fully depressed and you can hear the engine rushing but no speed up. no panel lights and it runs good int he city.
hose coming off the front of the trans bleeds like crazy, gonna get a new one down at autozone and go zipping around in my z24 love this car
mine they cut new cooler lines, installed, and they still leak. i think you need a really good transmission person to do the job right. The age of the vehicle too, since factory did not do a good job with the proper line installation on these cars.
My car went into the dealership for a trans filter and flush. It began leaking shortly after that. It went back and they claimed it was an aftermarket trans cooler. I had that fixed someplace else. Still leaking. When that happened, I went I went back. They are still working on it.
same as above .not repaired yet 'need to buy whole unit
Need an estaminet for repair at auto shop to repair transmission lines leaking fluid
rubber transmission cooler lines were fixed then leaked again. There is no permanent fix
