80w90 has anyone ever put these kind of junk in there tranny

 

no way man.. i stay with the gm syncro mesh.. you thinkin of tryin 80w90?? supposed to put regular 10w30 motor oil.. i heard of people having problems when they tried using thicker oil..

 

Gear oil is measured using a different scale from motor oil. When a gear oil is stated as 80W90, its viscosity is similar to common motor oil. It's not junk, and it's not eight times thicker or anything like that.

For example, Redline makes MTL transmission fluid which has a gear oil viscosity of 70W80. Its viscosity is between 5W30 and 10W30 motor oil. Redline also makes MT-90 transmission fluid which has a gear oil viscosity of 75W90. Its viscosity is closer to 10W40 motor oil. You'd want to use the MTL (70W80) or 10W30 motor oil in a cooler climate (like MA), and MT-90 (75W90) or 10W40 motor oil in a warmer climate (like CA).

I've tried Redline MTL and Honda MTF as well as synthetic 10W30 motor oil and didn't notice any difference among the three. Now I just stick with Honda MTF in my cars and it works just fine.

 

Well i've ran Honda MTF and Regular 10W30 oil in my tranny but it suck. I notice at cold weather its stiff, so I swith to GM Syncromess and I felt the different much smoother.
but then again I live in Utah during winter sometime I can get down to 20 degree with wind chill

 

my friend works at a local tune up shop and they use 80w90 for all their tranny flushes

I personally run honda MTF rather than motor oil, if you get a bottle of MTF and smell it it smells like *** and nothing like oil, there are different adatives and other fluids in MTF that coat and protect the gears better than standard motor oil

I doubt honda would take the time and money to produce gear oil to put in the tranny if you could just use 10w30 motor oil

 

If you run a KAAZ dif then you have no choice, Ill be running Torco GL-6 80W-90.

If you are not using the KAAZ dif, then I dont see a point in using it. Just use Honda MTF.

Yah, when i was reading about redline syn, i figured that it would be fine since honda fluid is a 10w30, then quickly found out its wayy too thin. Felt good at first - then it ATE up my synchros.
Redline synthetic for hondas
Honda MTL

Note - MTL is the name of the Redline product. Honda's product is called MTF (as in Manual Transmission Fluid).

oh, sry, i knew that.

correction:
Redline MTL
Honda MTF

 

im pretty sure 80w 90 is for differentials, its way to thick for bseries trannies.

Not true. Sounds like you didn't bother reading my first post, above...
