Pete, If I'm thinking of the correct part I can't see why the engine would come out for such a simple job. Just pull off the rear valance, center mufflers, transfer gear case and pull the mainshaft out. It just rides between the lower rear most splined transfer gear and the trans...it just pulls right out once the transfer gear cover is removed. Have any more questions feel free to ask. Regards, JRV | ||

I suspect that if this is similar to the 308 gearcase, the shift shaft has become misaligned and is selecting the "gearbox full of neutrals." I had this happen on Markys 308 when I adjusted the linkage and didn't tighten the jamnut enough. EZ test- take the shift gate loose and try selecting a gear with the gate pulled up and away from its mount. I think you will find the linkage has just lost its alignment. I hope this is your solution for your wallets sake  | ||

I agree with JRV. Check out your transfer case. Something is screwy in there. Have you had any recent clutch work? If so, I would suspect a fastener failure / loosening in the transfer gears. | ||

This doesn't make any sense to me: "if the car is on jack stands, and i put it in gearif the half shafts spin and the wheels don't broken cv's?" Do you mean that: the engine is running, a gear is selected, both drive shafts are turning, and both wheels are not turning? If that is indeed the case, the only explanation would be that both axles sustained simultaneous failures at either the outer CV joints or the stub axles (splined to wheel hubs). While this is possible, it is also almost inconceivable. The chances of both axles failing concurrently are extremely remote --- I don't buy it. I would examine things a little a more closely. | ||

Worst case $2.5K-$3K if the clutch output shaft snapped. I think the last output shaft I replaced 3-4 yrs ago (in a TR) was about $1.8K just for the shaft alone plus labor. If it just broke the snap ring and came loose, less of course. If it's wheel splines or stub axle splines or an axle/cv's or output hub less than above. | ||

jrv, if you would make a cost estimate for the different scenarios...how would that look? if anybody would know, i think it may be you! p.s. a nice ferrari story...my neighbor bill rhodes (real neat ferrari guy...won his class @ pebble with a 1 of 4 total production, 410 sa bodied 250) got up from his thanksgiving dinner and drove his race car hauler to come get the boxer and me. great guy! | ||

Hmmmm I'm speed reading again...lol... you can put the car in any gear without the clutch? the clutch output shaft could have come loose or snapped as suggested | ||

You can also just put the car in gear, engine off and see if it rolls or you can push it. I imagine you can see the outer joints at least without looking too hard. Its just easier than jacking it up. | ||

stub axle or splines into the brake rotor/hub or wheel pull the wheel/wheels until you find the problem | ||

thanks guys for the responses! before i go further, i hope you all have had a great thanksgiving...i have much to be thankfull for including this ferrari site!! back to the car. if the car is on jack stands, and i put it in gearif the half shafts spin and the wheels don't broken cv's? what other associated damage may i be looking at and at what cost? another question...i can have the car running and w/o clutch, put the car in any gear. does that defeat the cv or spline theories? i must say that up until the car broke...i was having an unreal drive! it is such a sweet machine! | ||

Not a lot to go on, however it does sound like it could be an axle related issue or clutch issue. BB gearbox's are bullet proof. | ||

Peter, Sounds like the CV joint on one of the half shafts has come apart or the flange comming out of the transaxle has become disengauged from the splines on the output shaft (rare but it happens). The other possibility is a snapped rear axle at the upright. All of these things are easy to check by just putting the car up on jacks and checking the half shafts for power transmition. Good luck, Robert | ||

Are the axles still connected to the gearbox? Are the axles ok, joints and so on? | ||

today, while driving along in trafic in 3 rd gear @4000 rpm, my bbi made a "clunk" type niose and acted as if it fell out of gear. i then depressed the clutch and tried to select 4th . nothing! with engine running i tried 5th ...nothing. coasted off into a parking lot and shut the car down. no oil under the car...bone dry. clutch slave is new and dry. gear shifter seems to be working and has the proper resistance when selecting gears. car just will not go...help!! -pcb |
