The engine and transmission have to come out together from the top and then separated once they are out of the engine bay.
You don't have to remove the engine to remove the transmission. You can support the engine with a support bar and drop the transmission through the wheel well by lowering the engine cradle. It is much easier this way and i have seen it done numerous times.
take a big screwdriver between the axle and transmission and it should just pop out.
The transmission is the same.
You need a different front end, transmission, transfer case, wiring, etc. Buy a different truck.
Yes, this will be safe to drive then in 2 wheel drive.
There is no way to answer this without more information. It could take as little as two hours on a simple rear-wheel-drive vehicle (assuming you have a lift and a transmission jack.) Or it could take two days to disassemble and reassemble the front frame of a badly designed front wheel drive car.
Get in the grass or gravel and floor it. If the front tire spins it's front wheel drive. If the rear tire spins it's rear wheel drive. If neither front or rear spins, take it out of park!!
The center shaft in a 2-wheel drive transmission is shorter then a 4-wheel drive transmission because the 2-wheel drive does not have a transfur case on the back of it. NOW, You can take the center shaft out of the 4-wheel drive trans. and install it in the 2-wheel trans. and it will now work in the 4-wheel drive vehicle. To change the center shaft requires both transmission to be taken all the way apart.
If you are talking push mowers - Go with a rear wheel drive. On front drive machines when you put pressure on the handles you take weight off of the front wheels and it doesn't want to go very well.
Find out where. Usually transmission fluid leaks from either the front or rear seal. The front seal (between the engine and transmission) requires that the engine or transmission be removed from the vehicle for replacement. The REAR seal (assuming Rear wheel drive) can be replaced by removing the driveshaft from the transmission tail. Front wheel drive vehicles typically have a seal on each of the "half shafts", and each manufacturer handles that differently. Sometimes you need to take the front end apart, sometimes it's just a few bolts. Sometimes it's an entire transmission rebuild.
Yes
NO.... The center shaft that runs through the transmission is SHORTER in the 2-wheel drive transmissions because there is no transfur case. 2 and 4-wheel drive transmissions will NOT interchange.
The center shaft in a 4x4 transmission is longer then a 2-wheel trans. so it will go into the tranfur case. You will need to take the 4x4 trans. apart and put a 2-wheel drive center shaft in it and then change the rear tail shaft housing on the transmission and then it will work in the car. It would be cheaper and easyer to just get a car transmission.
