hi,
can anyone tell me how many bottles I need to buy? I'd search but the search function doesnt work
thanks

 

i think you need 4 if you are doing both trany and diff. its in the haynes and FSM manuals. come on.......................

 

I bought three for just my trans used only a little bit out of the third bottle.

 

same

 

2.5 oz for the tranny (so 3 bottles) u should use only the regular 75W90 for the diff!

 

The Redline Shockproof stuff is best for the diff. (I forget the full name of the Shockproof)

 

I just did this not too long ago. I used the 75W-90 for the diff (buy 2 bottles, you'll use a little more than half from the second) and MT90 for the tranny (buy 3 bottles, use 2 1/2)

My experience with the MT90 is very pleasing. It takes about 500 miles to be broken in, and after that it's easy shifting 101. Never going to switch. Have fun beer bonging those fluids!

 

Exactly why is it so much better?

When you change the tranny oil, do you need to change the washer for the drain plug like it says in the fsm?

 

I couldn't tell you if there's something special in it or not, the reasoning behind me liking it so much was my 2nd gear was a bitch to get it to gear when I bought my 10AE (gear box is probably just now broken in) and after I put in the new fluid it started shifting a hell of a lot better.

 

So smoother shifting?

Did it reduce tranny noise?

 

Smoother shifting, yes.

Tranny noise? never had any to begin with

 

Hehe lucky you...

 

Summit Racing is the cheapest place to buy it I know of with really fast shipping.

 

I second that!

Much better than the MT-90

 

Do you feel results right away or is there a break in period?

 

I just put 75W-90 and felt the difference right away, omg it was so smooth.

 

the only difference I've noticed with the Redline MT-90 is that on highway drives, the shifter stick doesn't heat up at all.

Before, when I first got my car, the shifter would get quite hot after 5-10 minutes on the highway. Now, even after 2 hours, the stick barely gets warm.

Haven't done my diff. yet, because the bolts are stuck on there too well, and I'm always bringing the wrong tools with me when I actually go to do the job

 

I would worry if the stuff is made for transmissions.
GL-5 is not equal or supercedes GL-4.
The bottle should explicitly state "for use in synchromesh" transmissions.
Typical GL-5 "gear oil" includes sulfates as a bearing load enhancer; sulfates can eat bronze synchronizers in modern synchromesh transmissions.  This can mean you can get initial great performance, but shifting will start to grind over time.  You can easily tell if a gear oil has sulfates - smell it.  Sulfates STINK - Redline MT90 does not have that nasty smell to it.

I've seen the other thread that is similar to this where Icemark mentioned that the owners manual specifies GL-5 in the transmission, but I can't confirm that myself.  I prefer to stick to GL-4 stuff or if the literature specifically states it's okay for synchromesh transmissions.

I've got the 86 owner's manual right here.
