Re: Transmission Fluid Leaking?

Looks like the floor under my vert when it sits over winter. I have changed the front seal in the powerglide a few times but gave up after I drive it for the first time of the season it stops leaking till the next winter.

Re: Transmission Fluid Leaking?

It's very hard to diagnose a leak by looking at the spot it left on the floor.

Had it up on stands yet to look for drops hanging off of spots? I'd say get yourself some Rhino ramps, go drive it, come straight home and get it on the ramps, jack the rear end up and put stands under it, then lay under it with a flash light. That's the only way I found a coolant leak once on a truck that would only leak going down the road.

Would help if u also told us which ideas u gave checked todate

possiblities
1/pan bolts not torqued correct...
2/ trans cooler line cracked at the joint, or just inside replace
3/ Trans line nuts over torqued and distorted replace
4/ The nipples into thr trans over torquesd and hairling crack in the case...dismantle trans and grind out, tig weld and reassemble with new bushes and bearings
5/O ring around oil filler tune or distorted...replace.
6/Rear seal or front seal
7/ incorrect length bolts mounting the pump....cant mix aussie built trans bolts wih US built trans...If too long rebuild, if too short replace.
8/ over filled and spilling out the kick down seal.

I best way to fine a trans leak...because it can be very deceptive...is the car on a hoist, everything cleaned down, and run on thr hoist to try and dupilcate

My Spelling is not incorrect...it is creative

Re: Transmission Fluid Leaking?

If it only leaks after having set a long period of time, it's usually due to the fluid draining back from the torque convertor, overfilling the pan / valve body cavity, then leaking at either the dipstick tube o'ring or kickdown / shift shaft seals. If the pan gasket were the culprit, you usually have leakage while driving as well. JMO

Re: Transmission Fluid Leaking?

I agree with George and to add, the torque convertor fluid would leak through the oil pump and fill up the case and could leak out the vent on top right at the b/housing junction and points to the pass side.
This is normal if the car sits for some time. Every day driving, you won't see it.
As suggested earlier, check the fill tube and the kickdown cable housing first.

Number 9/ on my list lol
Since all my classics are driven daily, never seen that...and most rods in NZ, there is a run, show on everyweekend, not many (unless trailer queens) get a chance to sit that long.
