4+3 Overdrive service

[tnovot]

Does anyone have experience/knowledge about filter and fluid change on a 4+3 OD unit? Specifically:
1. what is the correct fluid capacity?
2. what is the best way to add the fluid - is there a special fill plug and and hose/funnel arrangement or is the fluid added to the pan before reinstalling?
3. is the OEM silicon RTV or a replacement cork gasket best to reseal the pan?
Thanx for any and all replies.

4+3 fluid change

Hi Terry,

When I did the change on my 86 I used the gasket & filter from Mid -America its $19.99,part# 603-817.
To fill I used small pump to pump the fluid into the tranny till it overflowed the fill hole.

When I tried the gasket (seemed like a good idea) it leaked. Had to go back to the sealant. Just a warning.

Terry,

Capacity should be just shy of 2 qts. I use a pump and tubing to fill the pan and I also use silicone instead of the gasket that comes with the Mid America kit.

Hope this helps,

Hi, I also went the cork gasket route, it leaked, used RTV black silicone no leaks. Don't forget to straighten the pan flange and bolt holes. Put a straight edge on the pan to check it. Don't use tons of silicone, it will squeeze to the inside of the pan and could be picked up by the filter impeding flow of ATF. Just my .02.

When I fill mine (there's a fill plug on the passenger side) I use a squeeze bottle with a flexible straw over the end. Nothing fancy - an old gear oil bottle and a kid's krazy straw do the trick.

You can get one of these pumps usually at any auto parts store. about 5 bucks. Fill till it overflows.
