So I've noticed my transmission having problems on my 89 FJ62. On the road when I hit the gas it will miss the gear and I'll red line. I'll have to pull off the gas pedal until it catches. Now this doesn't happen every time but enough to make me concerned. Today I went to put it in the low gear on the shifter and it wouldn't go in(not to be confused with low-range in 4wd). Then all the other gears were off, for instance the "drive" was neutral and "Neutral" was drive. It would stay that way until I would put it in park, then everything would line back up. Is it time for the H55 or is this something I can try to fix? And FYI all the fluids are good.
