It calls for a 75W-90 GL-3, and there were some years when the shop manuals
incorrectly called for a 75W-90 GL-5. Redline's MT-90 is a 75W-90 GL-4, MTL
is 70W-80 GL-4. If you go with Redline, MT-90 is the correct viscosity.

Thanks, Jerry. If he's in a cold climate he may want to consider the 70w-80
fort improved cold shifting. I put the original fill of Red Line MTL in my
'94 YJs AX15 at 30k miles. I changed it last year as part of the 60k
mainenance and noted the drain plug magnet didn't have a single flake of
metal on it. Great stuff!

The owners manuals for the YJs and XJs through at least '96 also called for
a 75w-90 GL5. I'm not sure when DC caught on and started using the GL3, but
before that MTL was about the only thing available that would stop the
synchros.

The 75w-90 GL3 sold by DC is quite pricey but works well. I put it in my '96
YJs AX15 three years ago and it immediately eliminated hard cold shifitng.
When I looked this a few months ago the dealer came up with two different
gear oil part 3's, one recommended for the AX15, another for the NV3550.
They claim to have used the latter with success in the AX15, but if one is
ordering this stuff might as well get the correct number.

Thanks, Jerry. If he's in a cold climate he may want to consider the 70w-80
fort improved cold shifting. I put the original fill of Red Line MTL in my
'94 YJs AX15 at 30k miles. I changed it last year as part of the 60k
mainenance and noted the drain plug magnet didn't have a single flake of
metal on it. Great stuff!

The owners manuals for the YJs and XJs through at least '96 also called for
a 75w-90 GL5. I'm not sure when DC caught on and started using the GL3, but
before that MTL was about the only thing available that would stop the
synchros.

The 75w-90 GL3 sold by DC is quite pricey but works well. I put it in my '96
YJs AX15 three years ago and it immediately eliminated hard cold shifitng.
When I looked this a few months ago the dealer came up with two different
gear oil part 3's, one recommended for the AX15, another for the NV3550.
They claim to have used the latter with success in the AX15, but if one is
ordering this stuff might as well get the correct number.

You are still confusing as ----. ;-)

Now you say it's 'ok' to use redline GL4, but don't do it because it's
supposed to be GL3 which redline doesn't make, but use redline because
it is better.

Oh and 'don't use 90 weight because it won't shift, but meanwhile 'you'
use MTL which 'is' 90 weight which is 'great stuff'.

So just what the heck is it?

'I' know to use the GL4 'gear oil' for transmissions and to make sure
it doesn't have the limited slip additive for differentials.

'I' could only find the GL4 diff fluid once when changing oil so used
it. My shifter stopped working shortly after.

'I' then went and found tranny gear oil which only came in a semi
synthetic at my local parts store, all the 'regular' gear oil had the
limited slip or friction modifiers in, and now I have a sweet smooth
shift.

You are still confusing as ----. ;-)

Now you say it's 'ok' to use redline GL4, but don't do it because it's
supposed to be GL3 which redline doesn't make, but use redline because
it is better.

Oh and 'don't use 90 weight because it won't shift, but meanwhile 'you'
use MTL which 'is' 90 weight which is 'great stuff'.

So just what the heck is it?

'I' know to use the GL4 'gear oil' for transmissions and to make sure
it doesn't have the limited slip additive for differentials.

'I' could only find the GL4 diff fluid once when changing oil so used
it. My shifter stopped working shortly after.

'I' then went and found tranny gear oil which only came in a semi
synthetic at my local parts store, all the 'regular' gear oil had the
limited slip or friction modifiers in, and now I have a sweet smooth
shift.
