I used the Blue Devil Transmission Sealer on a tip from the restoration shop. So far so good.
Noticed a bid puddle under the transmission. Haven't driven the car in months. Strange that a seal gave out just sitting in the garage.
Get the car to operating temp and with the engine at idle check the level of trans fluid
You may just be over full and leaking
Worth a look
If you are down fluid you would have to get back to your trans rebuilding people
The parts need to be used to work properly. The seals shrink slightly when the car sits this is normal. Cold weather could make it worse. Try Blue Devil Transmission sealer. It worked in my ‘69 and I just put it in my ‘64 that had all new seals but started to seep from lack of use.
If the torus converter check valve is leaking, then the fluid will drain back into the transmission when sitting. The trans will overfill and leak.
Please Keep us posted on the trans sealer you are using and your results for the longer haul
Never heard of that brand
It would be wonderful to know a product that would really work to seal the trans and prevent or reduce any leaking
My own experience that is very limited was not a good one
I bought a sealer for my power sterring years ago ( no idea the brand at this time ) and almost as soon as i added it all the fluid ran out of the power steering and had to replace the power steering unit in my 69 CDV
Just google it n Amazon and read the reviews.
