Default How difficult to change from jdm 6th gear ratio to JDM?

I have a JDM Sure-Trac. My 6th gear is just too low for my likeing. I would like to run the USDM 6th gear.

What would this encompass. I would imagine that it is the drive and driven gears that need to be swapped? Niether of these are part of the shafts are they? Would I be able to swap the 2 gears only?

I really want to have a highway gear. I like the rest of the gears, but I want a higher 6th for fuel economy and engine life.

Thanks, I appreciate the help,

I have the manual, and it would only require 4 parts. 5th and 6th drive, and 5th and 6th driven. it is actually only 3 parts because on either the drive or driven side, 5th & 6th are actually on the same piece.

Labor is now my only concern. For one, you have to find a mechanich good enough to do the work properly. I don't trust too many people working on my FIVE THOUSAND DOLLAR TRANSMISSION!!!

If you know what I am saying.

Any more advice?

this is why you make mechanics sign contracts before you allow
them to work on your car.

the contract must state that the transmission and car is in
perfect working condition, minus whatever isn't in working
condition; also that the mechanic agrees to replace or refund
any money or parts that become damaged and/or missing as a result of working on said transmission; that you only allow said
mechanic to preform said work (replacing 6th gear and associated
required shafts) with new parts, any extra work preformed is
considered free regardless of cause. also that the mechanic
must provide a reasonable turn-around time for the car.

look, find a lawyer to draft you up a contract, take your car to
mechanic shops and have the owner of the shop and the
mechanic who will be working on your car SIGN IT. the contract
needs to state that if multiple mechanics work on your car,
then anything that is damaged/missing would be a liability of
the shop or owner of the shop.

anytime you take your car to a shop to have work done, play it
smart, make them sign a contract. it's the best way to keep from
getting screwed. if they don't want to sign a piece of paper that
protects you, what makes you think they give a **** about you or
your car to begin with?

I've seen people been screwed out of tens of thousands of dollars
and had **** stolen off their car because they didn't protect
themselves in court

get an estimate, and put it on the contract that there should be
no more than a 15% variation in the estimate price on the bill
of sale, put the estimate value on the contract.

for work like this, if they estimate $1500 for the entire job $1800
should be the most they can jack the price up to.

I was quoted $125 for a new water pump and labor on my 94
ford taurus; it blew. what did the bill come out to? $179, he
replaced the pump, pump outlet hose and serpentine belt and
charged me a ****load extra.

protect yourself, if one shop won't sign the contract, another will.
if it's a valid contract and has been notarized, you can **** them
over in court if they try to **** you over in the shop.
