i was wondering is a s4 transmision fits up to the drive shaft, also i dont overheat but i loose alot or antifreeze and i dont leak...wtf. dont tell me im loosing a coolant seal.the brake goes to the floor and then works and the clutch looses pressure but i rebuilt the slave. oh and both dont leak anywhere. one more thing, is it true gtu's have turbo 2 componets i know mine has an aluminum hood so that was correct what i heard. just making sure they aren't all rumors. any advice would be nice.

 

Probably the master cylinder...in both cases.
You say they don't leak anywhere- and that's possible- but have you pulled the brake MC off the booster? It's relatively common for the MC to leak into the booster, which is not immediately apparent.

At any rate, when you find it necessary to rebuild one part of a hydraulic circuit, it's good practice to assume that the other components need at the very least, a close inspection.
Especially the clutch, it's so easy- and cheap- to just do the whole thing and be done.

 

An '89 "GTU" was the base car that year. Single piston front brakes, solid rear rotors, open diff, base suspension... not much in common with the Turbo. The "GTUs" might be the car you were thinking about. It had the same brakes as the Turbo, same seats, a limited slip differential (different axle ratio than the Turbo though), the same 16" wheels as the Turbo, and an an aluminum hood. The aluminum hood alone isn't proof positive that your car started out as a GTUs since so many parts get swapped over the years. Check the tire information decal in the driver's door jamb. If it specified 16" tires, you probably have a GTUs.

 

thank you both so much, it really helped alot. but yeah i think i got the gtu and gtus mixed up.
