You may need to elaborate more.... Is it in the Front, middle or rear.... Are you sure its transmission not engine oil? Is this a new leak or old? Was anything recently changed? Always a good idea is to do a good clean up and then try to locate the start of the leak... from there a solution can be determined.... Quote Link to comment
datzenmike Posted October 25, 2023 Report Share Posted October 25, 2023 There is a fill bung on the driver's side about half way up the case. If oil comes out it's over filled. When it stops put the bung back in. Over filling will cause the oil to foam and it will leak out the breather. Most likely is the rear seal where the drive shaft spline enters the rear of the transmission. Another leak source is the speedometer cable. Power wash the transmission clean and when dry, spray and rinse down with brake cleaner. Check regularly for signs of a leak origin. The front looks dry. Quote Link to comment

Chance Posted October 25, 2023 Author Report Share Posted October 25, 2023 @datzenmike @Crashtd420 It’s right behind the transmission drain plug on the passenger side. it seem to be leaking out of where the wires are. Looks like coolant. When I cleaned it up it comes from where you see the drip Quote Link to comment
datzenmike Posted October 25, 2023 Report Share Posted October 25, 2023 Check the washer isn't split. Or missing! 32005-21100 is the part number, if still available. If only used ones are available they are used on... SP/SR 311 Roadster '68-'73 510 '71- Mar. '74 1200 520/521 trucks '73 620 truck When done check oil level and top up. Quote Link to comment

datzenmike Posted October 25, 2023 Report Share Posted October 25, 2023 LOL. the reverse switch is likely submerged in oil so..... Quote Link to comment
Chance Posted October 25, 2023 Author Report Share Posted October 25, 2023 @datzenmike had no washer and some Teflon tape but wires snapped and the crimped connections came undone 1 Quote Link to comment
datzenmike Posted October 26, 2023 Report Share Posted October 26, 2023 Degrease and solder them back up. Easy fix. Quote Link to comment
Chance Posted October 26, 2023 Author Report Share Posted October 26, 2023 @datzenmike what size washer does it need? Not finding any of the switches that come with a washer. Some other forums are saying 1/16th thick. My reverse lights were working just fine without it. Maybe it was the bunched up Teflon tape that was making it leak? Thanks. Quote Link to comment

Try cleaning everything and not using the teflon tape... if it still does leak I'd use one of those copper drain plug washers that crush to seal.....

Yes I revised the text after, and added the comment about the washer. But as it turns out, no, the '73 620 switch does not show a washer nor any vehicle with the F4W63. 1 Quote Link to comment
thisismatt Posted October 26, 2023 Report Share Posted October 26, 2023 Is it a pipe thread? Yes? Teflon tape and/or pipe dope. No? No Teflon tape, no pipe dope. 1 Quote Link to comment
Chance Posted October 26, 2023 Author Report Share Posted October 26, 2023 Yes it’s for a 73 620 I’ll install with no washer and torque it down see what happens. Also does it matter what terminal the wires get soldered on to ? Quote Link to comment

Chance Posted October 26, 2023 Author Report Share Posted October 26, 2023 Could I just run it without the reverse switch? The terminals are all gunked up and solder won’t stick. Thinking of just tightening it up and going no reverse lights. Not tryna spend 45 bucks on a reverse switch. Quote Link to comment

1001001SOS Posted October 26, 2023 Report Share Posted October 26, 2023 If solder isn't working you can use crimp connectors, you don't HAVE to solder things. It's just a way to make a connection same as anything. How many joints in the stock wiring harness are soldered and how many use connectors? Connectors are fine, cleaning it up first is more important than anything. Quote Link to comment
Chance Posted October 27, 2023 Author Report Share Posted October 27, 2023 Crimped everything up, old wires not long enough to reach now after cutting and stripping. The wires coming from the harness weren’t event connected to eachother just touching in some wire insulation. Turns out the switch seems to be leaking from the plastic part where the terminals are. So probably gotta get a new switch and figure the wiring out. Quote Link to comment
