Are all manuel transmissions in trans am's T5. Including th V6 model 2.8L

 

No, the 82-83's had Super T10 4 speeds, I think. The T5 started in late '83, and continued until 1987 in our cars. Then for the '88 and up cars, the T5 was upgraded to hold a bit more power, and called the World Class T5.

 

so a v6 2.8L with a manuel transmission. doesn't have the T5 or the world class T5 in it? I plan on dropping in a 350 TPI in it and the world class T5 transmission is the best to go with to handle the power?

 

Yes, the v6's had the T5, but they aren't the exact same.
your best bet would be a T56 6 Speed from a 94-97 LT1 Firebird or Camaro, or an aftermarket T5 from G-Force, Tremec, or Richmond.

 

Im assuming that the world class t5 is a beefed up version of the t5, and what difference will there be with the G-Force, Tremec, or Richmond aftermarket t5 transmissions over the stock t5. which would you recommend out of them 3 and where would i be able to find one? the reason why im asking is i have an 85 ta auto v6 and i want to swap motor and tran out to a 5.7 tpi with manuel trans. im assuming the rear will need to be changed too because i believe my rear is limited slip. only one tire spins when burning out. if you have any tips on how to make this possible and what parts i need will be great.
