O ring on Tranny

[Nacho-RT74]

Does somebody know if is possble to change this oil seal ( number 52 on graphic ) without remove the tranny from the car or dissasembly less as possible.

[Chryco Psycho]

Yes  I know









Ok I will tell you , basically no , you need to remove the tailhousing , Pan & valve body minimum ot get at it

[Nacho-RT74]

ok, that's good tailhousing is not hard even I don't know why is necessary the tailhousing... I can't see relation there.

Valve body is what I was practically sure, beside release the reverse band to let free pressure on that piece

  because the pin that the o-ring is on is held in place by the tail housing.  or should i say isnt alowed to come out by the tail housing

This leak can be "fixed" without removing any components other than the pan. The exposed end of the shaft can be sealed with RTV to stop the leak.

In order for the RTV to stick to the area, the fluid must be drained below the level of the shaft. After the fluid is drained, use a punch and lightly drive the shaft as far forward as it will go. Then clean the area thoroughly with brake clean, blow dry and apply a liberal coat of RTV to the end of the shaft and the surrounding cavity. Let the RTV cure overnight before refilling with fluid.

This might seem like a Mickey Mouse repair but it works and is a lot less work than removing the tail housing and associated parts.

I think was already tried, but didn't work... unless the leak come from another part

If the RTV is applied while the leak is still present it won't stick, thus the need to drain before attempting the repair.
