88 Plymouth Sundance 5 Speed Trans Problem

88 Plymouth Sundance 5 Speed Trans Problem
Year: 1988
Model: Plymouth
Engine Size: 2.5 Turbo
Auto/Manual: Manual
Mileage: 75000

I have a 88 Plymouth Sundance. When I was going down the road it just seemed to pop out of gear and over reved. Now it won't move. I still have to engage the clutch to put into and take out of gear. However when I go to push it into gear without the clutch it will rock the car. I have jacked the car up one wheel at a time and turned them while the car is in gear and it seems to move the transmission rocking it, they will turn completely either side was hoping for free spin due to a CV boot but no luck. Any ideas.

Sounds like the clutch came apart internally.

Give yourself some room so you don't hit anything, then try placing it in gear, then depress the clutch to start the engine. If the car wants to move (even a bit) then the clutch is dragging, which means the friction material is scattered all over the place or is deformed and no longer firmly attached to the disc OR the center hub of the disc is broken. Any debris between the flywheel and pressure plate will give you similar symptoms.

If this is the case the clutch assembly will need replacing, which requires trany removal.

Pay attention to everything while removing the trans because you may find other issues. I have seen cars (different makes) that had broken input shafts where the clutch normally rides. IOW, turn the trany by hand and move it throughh the gears while it's out. Also look at the oil you drain from the trany for any signs of metal. Anything is possible with a 22 year old car.

K, Thanks I'll make sure to do that. But as for it being the clutch I can start the car in gear and it don't move, the only time I get any kind of movement is when I push from neutral into a gear without touching the clutch. Hard part is, I don't have a garage currently and don't wanna get into taking it apart unless I know I can fix it, and time wise because it will be outside,

Oh and IDK if this makes a differance but about a week before it went out I had to really rev the car to get it to move. Then the day it broke, I didn't have to, the car felt like new when it would take off.

Been there done that and 90% sure it'a a clutch issue, unless there's any unusual noise.

Let us know what you find.

Edited to add: Double check the collar where the release bearing rides to make sure there is not a wear ridge causing it to hang up.
