I guess this post serves as kind of an introduction. I need to do something with my tranny, your advice would be greatly appreciated.
I am currently living in Nicaragua and my daily driver is a 1994 land cruiser LJ79. It has the 3L diesel with a G52 tranny.
My 5th gear whines, not horribly, but enough to let me know at some point it will need some bearings. Well if I have drop the tranny why not swap it with something better?
The one thing that drives me crazy with this setup is the engine is screaming at highway speeds. This truck has 4.88 rears and at 80kmh it sits at 2500-2600 rpms.
So a tranny with a higher 5th gear would be ideal for me.
In the research Iíve been doing it seems the 1kz engine was mated to a r150 or 151, though I could be completely wrong. Obviously with the lower first ratio. The 151 seems very ideal. I could pick up a 1kz tranny with transfer case for about $5-700. I realize the output shafts are different, so the t-case is a must. Thereís also the option of possibly nailing down a h-series tranny. Would that be worth it for the puny 3L engine?
I donít do much off-roading, only when itís necessity here. I run open diffs as well.
Now here are my questions: besides the bell housing, what else would I need to change? Clutch, clutch cylinder, mounts, drive shafts?
Like I said, any advice you can give me on what tranny would best suit me and any other important information, all would be appreciated. Also, how to tell these trannys apart from the rest would help me a ton!
