How can you tell the difference between 282 and 284?? Stamps on the trans??
5 Speeds, The Isuzu 5 speed attached to 85-88 4 cyl Fieros is not a good choice for a high torque swap, it is not strong enough. This transmission may cause problems because of weak cast alloy (pot metal) shift forks, which could break if abused especially at high rpms. Careful shifting can make these transmissions survive since it is the shift forks, and not the gears, which causes the problems. The gearing of the Isuzu transmissions seems to be a better compromise than the Getrags, but the reliability issue can cause some concern. This leaves the Getrag, although not perfect it is probably the best transmission used in the Fiero. It is strong enough for the high torque V8s and V6s but with the better ratio spread necessary for the cammier engines such as the 3.4 twin cam V6, the Quad Four and some V8s tuned for top end power. If you have one this is the transmission to use for any swap.
