Larry, I think you're putting the cart before the horse. You need to be our 'eyes' before we can comment. I strongly suggest you put the car in the air and take pictures of the problem. Otherwise, how would anyone know? - Dave

Default location of the leak is dripping onto the rear housing.

Then down onto the floor. So its either the rear seal or the spline seal.I no you just unhook the drive shaft and pop out the seal. Maybe making it sound to simple. So how many hours would a mechanic at a transmission shop take. And what cost would I be looking at. If it is the rear seal would a napa shop be able to supply it. Thank you Dave. 1962 bird

If it is the extension housing rear seal leaking, you also have to check the rear bushing and yoke condition as well as the front u-joint.

There are special service tools available to replace the seal/bushing on the car.

Default leaking in the rear of tranny

Thank you Kultulz. My situation is the symtom is this. Last Sat around 6.00 pm when I pulled outof the garage I noticed a small puddle in the rearof the tranny. From there I have started the car up twice no more leakage through 10.00am monday morning. Could the rear assembly housing hold fluid and when it gets so much into it spills over unto the floor. How would you explain that to me. This is a 1962 t bird with 56000 orginal miles on it. Purchased a rebuilt short block from Mr John Draxler two years ago everythind find there. Thank you. Larry

When you shut down the engine, the transmission fluid circulating in the trans assembly returns to the pan.

If the transmission is over filled, and/or if the case vent is not working properly and/or if the converter is leaking down, the extra high fluid level will flow to areas not designed to hold that volume/weight/pressure.

Do you have a shop manual (or use the URL I presented) to actually view the trans assembly and see possible leaking points?

Correction-

The manual I showed is a 1958 FORD manual. I just noticed you have a 1962 BIRD, but the illustrations for the CRUISEOMATIC in the manual will be much the same as your year CRUISEOMATIC.

Default case vent

hello again.

What is the purpose of a case vent on my 62 tranny What would it look like. Could it be cleaned from the outsde with solvent. Where is it located at. Thanks. Larry.

The purpose of a vent is to relieve internal pressure from the transmission due to the fluid being pumped. Think of it as similar to the engine PCV system.

I know the LINC HX went to an internal vent in 1962 and vents itself inside the bell-housing. I would think the MX does the same. It would have to be disassembled to clean.

I would go more in the direction of a bad rear seal first.
