while removing my motor and trans my transmission fluid got contaminated so i'm planning to do a drain and refill. Does anyone know what fluid to use to replace the existing fluid...with auto transmissions it's a no brainer but i haven't had to do anything with manual trans fluids before. To clarify my truck is an '89 22re 5 speed manual 4x4

thanks

 

Marshmallows.

 

What size are you runnin? Ive got the little tiny ones for hot chocolate in transmission. Ill probably switch out to the normal size for winter

 

Nice!

I use gear oil, 75/80w90 typically.

thanks guys. I thought you might like to see yesterdays biggest accomplishment from my end

 

 

okay, so the next thing I need help with is posting photos from photobucket

 

I use Redline MT-90

 

yeah use 75-90. I used Amsoil Severe gear which turned out to cause the truck to shift really hard. I ended up draining it, putting it in my diffs and getting Amsoils MT (same weight, both GL-5's too i think) and it shifts much smoother now.

Get a pump. I used gravity by zip tying a funnel rigged to tubing to my mirror and waiting a long time between quarts. Not the perferred method.

 

GL-4 is what u want 2 use in your manual transmission! but its hard 2 find around here unless u order from net

 

You'll need some kind of pump to fill it. Otherwise, I like to just pour it in through the shifter hole.

 

I justttt did this today. Put in the Redline MT-90 like someone else has mentioned. So far, the total of 15 miles i have put on it since i changed it... its great. I can now downshift from 5th to 4th to 3rd with out having to match revs. 2nd is still whorish, as i think i have burnt up that syncro a bit. But over all its much better. Much less "notchy" feeling and shifts more like my truck used to 5 years ago before i ran my clutch out of adjustment for 20k.. plus a bad main bearing? i think .. mixed in for a while.

I would recommend the MT-90 for sure.

How i changed my fluid:

-Drained old fluid into a bucket.
-removed side fill port
-found a small, around 1/3 litre plastic bottle with a cone screw on top, like you would find on an old style mustard/ketchup bottle?
-repeatedly filled up the small bottle and squeezed fluid thru the side port till it started coming out.

Probably more slow and painful than other options but i didnt have a pump and didnt want to deal with taking apart the shifter console area again.

 

you can use gl4 or gl5 that what the toyota book says...
