Behind the 258? It should be fine as long as you don't try to thrash it like a racer or go crawling with it. This is the best transmission you could get for plain highway daily driving because it's so lightweight but that's about all there is to it because it IS somewhat weak. This is a light duty transmission that I would compare to the AX-5. Still better than the SR-4, T-4 and just about every automatic. I would use it until getting an AX-15 or a mass miracle like the NV3550 becomes available. World class or not, a T-5 should last you many thousands of miles.
