Not very easily if at all, and why would you want to?

The car has only one transaxle, AKA transmission, then no, you cannot remove the tranny without removing the tranny. If you mean without removing CV Axle or drive axle or Axle shaft or CV shaft (same thing) then the answer is still no. You cannot remove the transaxle without removing the drive axle/CV shaft.


To summarize extremely, follow the same steps for removing the engine and transaxle separately with one important difference. Instead of being able to access the transaxle to frame mounts from inside the bellhousing, you would remove the crossmember by loosening the two large nuts holding it to the frame horns. Of course you would need to remove or disconnect all lines and hoses and wires as you would for engine/ transaxle removal. It is easier to deal with removing the engine first and then the transaxle separately, but it can be done.


Disconnect the negative battery cable. Properly drain the transaxle. Remove the air intake duct. Disconnect the TV cable. Remove the shift cable and bracket. Tag and detach all necessary vacuum lines and electrical connections. Remove the power steering pump and set aside. Remove the transaxle filler tube. Install engine support fixture J 28467-A or equivalent. Remove the top engine-to-transaxle bolts. Raise and safely support the vehicle. Remove both front tire and wheel assemblies. Remove the left splash shield. Remove both front ABS wheel speed sensors and the harness from the left suspension support. remove both lower ball joints. Disconnect the stabilizer shaft links. Remove the front air deflector. Remove the left suspension support and both drive axles. Disconnect the engine-to-transaxle brace, then remove the transaxle converter cover. Remove the starter Unfasten the flywheel-to-torque converter bolts. Disconnect the transaxle cooler pipes. Detach the ground wires from the engine-to-transaxle bolt. Remove the cooler pipe brace and the exhaust brace. Remove the bolts from the engine and transaxle mount. Support the transaxle with a suitable jack. Unfasten the transaxle mount-to-body bolts. Remove the heater core hose pipe brace-to-transaxle nut and bolt. Unfasten the remaining engine-to-transaxle bolts, then remove the transaxle assembly from the vehicle.


Remove four bolts that hold transaxle remove belt pulley and belt guard. remove shift linkage remove spring tensioner. then remove whole transaxle. Remove four bolts that hold transaxle remove belt pulley and belt guard. remove shift linkage remove spring tensioner. then remove whole transaxle.


This is no easy task, I suggest you get a service manual. It involves removing the battery, starter, transaxle support brackets, power distribution center, axle shafts, and the transaxle. Might be easier to just remove the engine.


Yes. You remove both engine and transaxle with the sub-frame at the same time out the bottom.


Yes, the engine will pull right out without removing the trans.


Without removing and disassembling the engine, Sea Foam oil treatment is a good product for this.


1. Disconnect negative battery cable. Remove battery and battery tray 2. Remove the air intake duct and the air cleaner housing 3. Disconnect the transaxle ground cable and the transaxle range sensor 4. Disconnect the transaxle harness connector from the side of transaxle 5. Drain the transaxle fluid then disconnect the transaxle cooling lines 6. Remove the upper transaxle-to-engine mounting bolt 7. Raise the car and support it on jack stands. Secure the engine with a engine support brace or with an engine lift and chain. 8. Remove the transaxle mount bracket 9. Remove the front wheels 10. Remove the bolts from the center member and the transaxle roll stopper 11. Disconnect the lower control arms from the steering knuckle and remove drive axles 12. Remove the transaxle stay followed by the bell housing access cover 13. Remove the torque converter bolts. A screwdriver wedged in the ring gear teeth will keep the torque converter from rotating. Rotate the engine for access to all bolts 14. Support transaxle with transmission Jack to lower transaxle from car 15. Make final check everything is disconnected 16. Remove the mounting and retaining bolts and lower transaxle from the car


Remove engine and transaxle assembly


It's almost impossible without removing the engine, unfortunately.


Yeah it looks tight alright, but after you remove all the accessories, and drive pulleys, you would have just enough room to sneak the engine out of there leaving the transaxle behind.


You can replace all of them BUT the 2 in the rear of the engine block with out pulling the engine. To remove the rear ones you can either pull the transmission are remove the engine your choice.


Yes. You need to unbolt the exhaust pipe from rear manifold and support engine and transaxle from above with engine hoist. Unbolt engine mounts and raise engine/transaxle to make clearance to remove oil pan. This is for V6 3.0 L engine. Yes.

You need a cherry picker with a leveler bar to be able to take the engine and tranny out in one piece.

Yes, all transmissions can be disconnected from the engine. I recently did just that but wasn't fun.. To remove engine with transaxle left in car you have to take everything off down to the block.. Putting back in you have to disconnect cv axle on passenger side from transaxle then motor will go back in..


That depends on whether you have a manual 5 speed or an automatic. On both you have to support the engine from above since 2 of the 3 mounts are on the transmission. Disconnect all the electrical connections. Remove the bolts and nuts that hold the left hand engine mount. Remove the upper front and upper rear bolts that hold the trans. to the engine. Remove the starter motor. Remove the drive axles. Drain the transaxle fluid Remove the crossmember. Unbolt the gear shift rod from the input shaft of the transmission. Remove the nut that holds the gear shift bar to the transaxle. Then slide the bar off the stud. Remove the clutch slave cylinder. Remove the 2 lower bolts that hold the transaxle to the engine. Put a transmission jack under the transmission Remove the catalytic converter. With the transmission supported well, remove the last 3 bolts that hold the engine to the transmission. Carefully lower the transaxle and slide it from the engine.


Begin by removing the engine wiring harnesses. Remove the motor mount retaining bolts. Disconnect the engine from the transmission. Lift the engine out.



# Disconnect the negative battery cable. # Raise the vehicle and support it securely on jackstands. # Drain transaxle lubricant. # Diconnect the shift and clutch linkage. # Detach the speedometer cable and wire harness connectors. # Remove the exhaust system components for clearance # Support the engine.This can be done from above with hoist or place a jack with a block of wood under oil pan. # Remove any chassis or suspension components that will interfere with removal. # Disconnect the driveaxles # Support the transaxle with a jack then remove the bolts securing the transaxle to the engine. # Remove the transaxle mount nuts and bolts # Remove starter # make a final check that all wires and hoses have been disconnected then carefully pull transaxle nd jack away from the engine # once the input shaft is clear lower transaxle and remove it from under car. # DO NOT DEPRESS THE CLUTCH PEDAL WHILE TRANSAXLE IS OUT OF THE VEHICLE.



yes. you drain as much engine oil from them sump as you can by undoing the 13mm sump plug. you then undo all the bolts holding the sump onto the engine


To change the flywheel or flexplate you'll need to remove the engine, transaxle or both. The flywheel or flexplate is between the engine and transaxle and is easily changed once you have clear access to the space between them.
