Hope I don't break any forum protocol, but I am in a tight situation here. I just bought an '85 GT 5.0 5 speed. I absolutely love this car, but the tranny has a hooped 4th gear. From the research I have started, it seems to be a common problem? I need to get this thing going ASAP and am dropping it off at the tranny shop tomorrow. Is it worth rebuilding the stock tranny? I heard T5s are junk. Is this true? If it is, what should I replace it with? If I should rebuild it, what should I make sure they do to it? I plan on getting the motor into the 350-400 HP range, I do a lot of street driving in heavy traffic (Los Angeles) not much drag racing (some sreet drag nights), some auto crossing and a lot of highway driving.

Thanks for any and all help!

 

400 hp+autocrossing= broken t5. get a tko 600 or something.
