I need to drain fluid out of a 95 truck tranny, and I dont know what to use to get the fill plug out... is it an allen wrench? what size?

thanks

 

If a socket head plug, usually 10mm. Stock plug should be a hex head, near the backup light switch. Forget the size off-hand, maybe 14 or 17mm.

 

thanks roger, your the man. I tried a 3/8" allen wrench, and it would grab, but wanted to strip it, so you think a 14mm is close to it?

 

As I said, if it is a socket head plug, then 10mm allen (and 10mm is a tad larger than 3/8"), if hex head (like a bolt), then 14 or 17mm, whatever fits.

 

Careful with that...it should be a metric which will be a hair larger, you may strip it.
10mm allen = 0.394" while a 3/8" allen = 0.375" .....I wouldn't risk it

 

Manual trannys have fluid?

If so, is it supposed to be changed at some interval?

 

Yes, they have fluid.

You can check here for intervals:

its a 10mm allen head...... if you strip it out.... you can get a new one @ the toyota dealer really cheap... i have the part # listed in my truck buildup in my signature

 

#90341-18021 drain/fill plugs
#12157-10010 alluminum crush washers

im stealing this picture from marlin crawler for illustrative purposes... they als osell them too, if you wnat to go that route

 

Only goes back to 1997 - mine's a '93.

Of course there would be lubrication in there - I guess by "fluid" he means gear oil?

 

Well that was a PITA!!

I think I got more oil on the driveway than in the tranny

Before I could read any replies, I went ahead and figured if the 3/8 almost fit, 10mm it is, and picked one up.

I will be buying a plug from the dealer and drilling and tapping a nipple onto it to aid in the fluid transfer next time.. I figure run a 1/2" OD hose from the nipple/plug to the gear oil and let it drain... I plan on sawing a notch in the threads to both vent the tranny, and allow fluid to seep out when its full.

for the guy who didnt know about the tranny fluid, it 75w-90, GL-4 or 5 , about 4 qts
