Verso semi auto box .

Assuming a traditional design it is probably rust and if fitted with a clutch pilot bearing, the gearbox shaft could be seized into it meaning considerable force might be needed to remove it. I have known them to be so seized into the pilot bearing that removing the gearbox actually pulls the bearing from the housing.

Give more information. What car, what year model? If there is oil where the flywheel is, chances are you have a leaking rear main bearing oil seal or leaking gear box primary shaft oil seal. Coil packs? They should be there to make the car go.

why are you replacing the bellhousing?,it means you are going to have to pull out the motor or the gearbox/transfer case,whichever is easieast

Hi Craig,
I'd suggest that the oil seal which seals between the torque converter neck and the gear box casing is damaged and will need replacing. The job seems simple but in fact can result in breaking the gearbox oil pump, when the torque converter is refitted to the gear box. the neck has to align with the gears inside the gear box and the oil pump, if the torque converter is not fitted correctly the damage I've mentioned will take place when refitting box.
If you would like to proceed let me know.

There is a cover on the back of the gearbox, Remove the cover and wedge 5th gear and reverse off the shaft. One that is done you must remove all the bolts around the bell housing. It might be that the 2 casings stick to each other because of the sealer used to seal the gearbox. The casings should slide off once the sealer has lifted.
