Automatic transmission...died...some questions
.It looks like my 4th gear is out...no where to be found.In 1st it takes about 4500 rpm before it wil shift,2nd seems okay.On the highway at 100 km/h it reads 2500 rpm and will not shift into 4th.So I guess my gearbox is shot.How many of you guys have changed their auto transmission on the floor.Can it be done on jackstands??We have a litlle lift that levels the car at about 1,5 feet high.(45 cm)
Do I have to remove the tunnelplate?
Do I have to remove the torque tube?
Just need some info guys wether it can be done at home without any specific tools.
Thanks in advance, Greetz Erik(Holland)
So in a few steps:
1 Remove the rear cradlle
2 Lower the diff and gearbox
3 Unbolt the gearbox + diff from torque tube?

You will have to get it rebuilt.
To take it out you should have no problem removing it and leaving in the tunnel plate. If it seems too tight then remove the tunnel plate and support the Torque tube.
You'll be suprised how easily the cradle and rear diff comes out along with the transmission.
Use a tranny jack to support the diff and trans, you will not have to be too high in the back with the Vette either.
Hope all goes well.
See the For Sale section VADER 87 Has a good used tranny for sale.

You wnat to get the most clearance that you can when jacking up the car.
Once you have the car in the air.
Follow one of the removal guides out there for manual tranny.
-There are some differences. You need to drain tranny and rear end fluids.
-Disconnect tranny cooling lines and shifter cable. Also remove all electrical connectors from tranny.
-Unbolt and slide off of torques tube. Make sure use a tranny jack, it will make job easier.
Maybe some pics will clear things.
PS ,thanks for the replys sofar...I really appreciate it!!

Do You have any info about that ?
Someone aid that it`s easier and cheaper to buy another vette with manual transmission than swap them.

It's not a job for the novice. I had a lot of support from Dr Phil, DTE, ECS and RPM.
The process requires gathering all of the parts and then some re-wiring.
The amount of re-wiring is dependent on wheher or not you swap out the tranny wiring harness or use the existing one. I choose to swap out the existing one.
Cost are dependent on a number of variables. I knew one day that I would want to make a lot of horsepower so I went all out.
- Clutch and Brake Pedal Assembly from a stick shift car.
- Manual wiring Harness from a car that was produced close to when mine was.
- Textralia Twin Clutch
- 2003 Z06 Torque tube and bell housing. Rubber front & aluminum rear bushings.
- RPM stage V tranny (base unit was a MN6).
- DTE Stage V Rear Differential and Brace.
- Other miscellaneous parts (fluid, tranny mounts, wire, switches, etc.)
Total parts cost was north of $10K. I will probably recover about $2K from the sale of the automatic drive train and associated parts.
If you don't crazy like me you could probably do the job for around $2 to $3 thousand, net. (Sale of auto parts).
If I had it to do over again, I probably would have hauled the car off to RPM to do the job, but at the time it just wasn't feasible due to all of the other in process projects.
If you need any additional info just drop me a PM.
