I'm a noob, whom has just bought a '96 lx 450. I'm in the process of baselining it. One thing that I have noticed is that there is a stutter and a hesitation in second gear under moderate to heavy load (ie. accelerating hard uphill) It usually happens between 1500 and 2600 rpm. It does not do it in any other gear. I have flushed the transmission and replaced the fluid. I have not yet done a tune up. I searched on the forum but have not come up with anything that helps. I could have missed something though. I thank everybody in advance for their time for helping point me in the right direction.
