1995 ford bronco leaking oil between transmission and motor. what can it be? how can it be fixed? thanx?

Common.





Most probably its the rear main seal of the motor.





Big job to fix, time wise. You need to split the box from the motor, and depending if its a rope seal, or a rubber seal, depends on what else you need to do.





If its a rope seal, you need to pull the crank out, as there is a pin that holds the seal in place, and you cant install the seal without pulling the crank.





If its a rubber seal, you can remove and instal the new seal with the motor in place,





Either pretend its not there, top up your oil and throw a stop leak into the motor, or do the job.1995 ford bronco leaking oil between transmission and motor. what can it be? how can it be fixed? thanx?
If oil is leaking between the engine and transmission most commonly it is the rear main seal. This seal is the very last crankshaft main bearing seal and is common to leak on any type of vehicle after extended mileage.





The only way to fix the rear main seal on a Bronco is to remove the transmission (which also requires removing exhaust components, the starter and a crossmember). The task of removing the transmission is not very difficult when you have the right tools and have access to a lift. Otherwise, it can get tricky when you are doing it in your driveway, but doable nonetheless.





If your Bronco is 5.0 or 5.8 the job is relatively the same. The only difference is going to be weather or not you have an automatic trans or a stick. If its an auto, just remember to remove the flywheel-to-torque converter nuts and keep the torque converter in the transmission. This will allow for easier installation after it is removed and you won't have to re-index the torque converter before you put it back in.





If after all this it sounds like a job you want to take on, then just be sure not to damage the area where the seal sets. Any burs, debris or irregularites in the metal will negate the entire job and you will be doing it again because it WILL leak. Be careful when removing the old seal not damge the crank or again, like I said, you will be doing the job again.





I hope you can fix the leak, good luck!1995 ford bronco leaking oil between transmission and motor. what can it be? how can it be fixed? thanx?
Transmission fluid or Engine oil? Red or Brown? If it's red, then perhaps the front pump seal or input shaft seal on the trans. If it's brown then I would suspect the engine rear main seal. Any of those seals are pretty pricey to replace-maybe a bottle of sealer instead. Good Luck
If it's motor oil it's the rear engine seal or possible the oil pan. If it's transmission fluid it's probably the torque converter seal or the transmission seal. All are a pretty expensive fix.
It is a rear main seal that is leaking. It can be found at any auto retail shop. The one for that truck ranges from $10 - $26 dollars.
I believe theres a seal between the two and it sounds like its the problem. The seal is not expensive, but the labour is.
its the seal of the oil pan or the crank shaft about the same... tough to fix sometimes.... and best if had done at a shop
rear main seal , drop trans and replace seal.
