Hey everyone,
OK so I have to change the engine oil on my '06 GT and was planning to do as well the transmission oil.
But I asked my mechanic about the rear transaxle oil and he told me that I don't need to change it unless it's leaking.
Do you guys know anything about that ? We really don't need to change the fluid for the transaxle ? Is it good for the car lifetime ?
thanks a lot to everyone

 

Trans fluid needs to be changed somewhat regularly if its an auto. As far as gear lube goes, it can't hurt to change it but its probably not necessary.

 

OK thanks So I guess I do not need to change it, no leaks and never went into water.

 

I typically don't change the oil in the differential until 100k or so.

btw - you do not have a transaxle in a Mustang GT. You have an engine mated with the transmission, then a rear axle differential (Traction-Lok) connected with a drive shaft.

Whereas most mid engine cars have an engine mated with a transaxle - where the transmission and differential are an integrated unit. Notice how the axle (half-shafts) mounts are located at the transmission - no drive shaft needed.

Changing the rear end fluid is overkill just spending an extra 50+ bucks

 

Thanks everyone I learned a lot with you.
Being French, I don't know all the technical terms for all this stuff.
