Outer Limits 4x4 Board

We have a 2001 GU 4 door auto tranny with the TB45E engine and it has the "HG 39" code (which i assume it has 3.90 gears), after putting some 33's it feels a little sluggish, the front diff is a reverse rotation h233 and the rearend is a H233B with disc brakes (NOT a H260, this is smaller), if somebody wants to sell the ring and pinions for both axles, and then deliver them to Chile (south america) please let me know.

Thanks

I would be surprised if a set of 4.1 would not fix your problem. Cheaper and I assume easier for you to find locally. There is less ratio change between 32" and 33" tyres than there is between 3.9 and 4.1 diff gears.

edit: none up there at moment, but sedn him a message

Thanks for the replies.
Anybody knows what's the OD ratio of the auto tranny? so i can calculate the difference between 4.1 and 4.30 gears

i have a genuine gu front centre 4.3 ratio just overhauled $350

Not sure of the OD ratio but the basic but approximate way to calc is divide by the 2 ratios. To be honest, unless the GU was running some non-stock, super tiny tyre to start with like 29"s, you should not notice any difference at 3%. Maybe it's only added tyre weight that seems to be affecting it.

IE

Difference between -

33" / 32" = 3.1% taller ratio

3.9 to 4.11 is 4.11 / 3.9 = 5.3% lower ratio
3.9 to 4.375 is 4.375 / 3.9 = 12.2% lower ratio


Bare in mind, these are only quick and dirty ways to make these calcs but they're pretty close and real world will only be fractions of percentage differences.

I sent you a PM

I priced BRAND NEW genuine nissan 4.3's front and rear for about $1500-

What's that compare to what prices others have been quoted ?

So nobody has a front set to sell? a friend has a rear ring and pinion off a V6 Pathfinder with the H233B rear axle, it has 4.30 ratio and he sells it very cheap... but i need the front set i can import it from Japan with the local Nissan dealer, but first is way too expensive, and second, it took about a month
