4 speed gear oil change
« on: June 28, 2023, 02:37:01 PM »
1980 Pony, 2.3, 4 speed manual. Wanted to change the lube in the gearbox with some fresh GL-4. However, searching the forum gave mixed results on wether or not there is a drain plug on the trans. So, do these things have drain and fill plugs or not?  If no, besides dropping the trans, are there any methods to perform a lube change?  If it has a fill plug, is it feasible to use a suction pump to drain it?  Appreciate any advice.

In 1984 I changed a clutch in a 77 with a 4-speed.  I don't recall whether or not there were drain and fill plugs, and because I don't remember, that leads me to believe that there were plugs.  If there weren't, that would have been an oddity and I think I would have remembered that.  The 1982 EXP with a 4-speed had drain and fill plugs.  Granted, it was a transaxle (FWD), so I am 99.9% sure your 80 4-speed will have drain and fil plugs.

My 1973 2.0L 4 speed does not have a drain plug, but strangely enough it does have two plugs, both on the left side. The BOTTOM one is the fill plug. I don't know what the top one is for. You can pump some of it out, but there is no way to get the sediment on the bottom out, and to me that's the important part. I found a lot of it in the rear axle, and flushed it out with brake cleaner. I don't think these cars were meant to be serviced. There are no grease fittings on the ball joints or tie rod ends.
