Hey everyone,

I have an original 1978 Pontiac T/A with the 400 W-72 linked up with a 4 speed Borg & Warner Super T10. I recently started hearing transmission whine in reverse, signals to me that it's time to add some fluid...

The car only has 60k original miles on it, but it leaks here and there and the more I think about it...the fluid it probably 30+ years old so its about time to change it out.

Any suggestions on what type of new fluid to put into it after draining out the old. I heard the new transmission fluid doesn't sit well with these older units. Also any idea how many quarts it'll take? I figure it'll take maybe 3-4 quarts and I've heard you fill it like a rear end gear....basically fill it through the side port until it comes back out (level with the side port hole).

Any suggestions?

hmm... suctioning the fluid out.. if there is no drain.. there might be on that one..

refilling with fresh..

its its howling in reverse.. it might be a little late...

i was just thinking.. and this is a bad idea.. hmm.. T10.. transam.. hmm.. how about the T10 4+3 out of a mid 80s corvette..  probably need to mod the transmission tunnel.. there are ways to rig the switches to keep it in over drive in second, third and forth..  this is a very WRONG idea..

Hi there....Richmond Gear now produces transmissions based on this design, the super T10, and they say that 1 and 1/4 quarts of GL6 gear lube 85-90 wt is the right fill for this tranny.  They sell their own brand of course, but say any similar lube is ok, including synthetics.  I'm pretty sure that you will find that if you fill to the fill opening, that will work out pretty close to what they say it takes.  
Virtually any auto parts store will have a small hand pump that fits the lube bottles which can both be used to pump out what ever is left of the old stuff if there is no drain plug, and can then be also used to pump in the new.  

Here's a link to their owner's manual which has a lot of info you might be interested in.

Well...that link may not work, but you can copy and paste it to get there anyway....
Good luck!

It takes around 2.4 pints of GL-4 oil. Just fill it until it pukes out the fill hole

You can use 75w-90 or 80w-90. Amsoil MTG is 75w-90 and is GL-4 comparable but is synthetic. The bottle says "Designed for Super T10 Transmissions.

I think the moderator will suggest you use the GL-4 80w-90 non synthetic.

Oil ain't gonna fix your reverse noise.

You use the sight plug (like the rear end) and regular 80w-90 is fine (like the rear end).  Capacity is about 3 pints.  Good luck.

First of all, thanks everyone for your responses.

It's not quite "howling" yet in reverse, just slight noise, figured new fluid would be good for it since I do drive it weekly. I went online and looked up fluid for it, not sure what weight it requires though...thoughts on this...

from my previous post.

"You can use 75w-90 or 80w-90. Amsoil MTG is 75w-90 and is GL-4 comparable but is synthetic. The bottle says "Designed for Super T10 Transmissions."

royal purple stuff is good however synthetic oil might leak from your trans.

the otrig was 80-90w. of you just drive 5 miles sat a time and then let the car cool off i might run 75-90w because the trans isn't getting that hpot and it might shift a hair better when its cold.

i would not run synthetic, no real reason other than possible leaks.

no need to dump expensive synthetic gear oil on the ground! use the cheap stuff. as long as you keep it full it won't matter. some king of friction modifier couldn't hurt.

Update:

Hey everyone, got the fluid all swapped out. It took around 2qts before throwing up out of the fill plug. Running great and shifting easier Grin

On a side note, rolling around on the ground trying to jam the nose of the gear oil bottle in the fill plug while in the car....well....was a challenge. Had to find the right angle to get it in, but after a half our of cursing and rolling around. I filled it to the top and fractured my tail bone doing so.

Glad it working good for you now.  At the parts store near the gear oil display, or in it, you will usually find one or two plastic hand pumps that have tubing that goes into the bottle of new lube, sucks the oil into the pump, and another piece of tubing that then goes from the pump through the fill hole in the trans or rear.  Inexpensive, and very worth the money.  Remember for next time.....
