tranny swap??

[vagabond]

havent checked yet but I think Im going to need a tranny replacement for my 88, somewhere on the forum there was mentioned an upgrade for the 5speed tranny,

Im running a jdm 3.3  engine, 95 electrical from tail lights to headlights, 95 dash, and if I read the tag right it has 4.36s gears and it feels like it.

 any thoughts on an upgrade on the manual tranny,

thanks in advance

The only upgrade I'm aware of is that Nissan moved the fill hole up a bit around '96 to raise the oil level. The oil level in previous years was too low, which tended to starve the countershaft bearings, leading to a whine in every gear but fourth. You can accomplish the same thing by overfilling an older gearbox through the shifter hole, but yeah, if you've got the option, the newer box would be easier to fill and less likely to come with bad bearings.

 

Also make sure you put the right fluid in it, the synchros do not like GL-5 oil.
