Where to start ? : Faulty gear box and repair

[Peter.N.]

The car in the picture has the engine the right way round, they were much easier to remove than the front wheel drive ones are, I might have a go at a RWD but I think I'm to old for a FWD.

I did repair the box for my sons Ford Ranger but that was on condition he took the box out and put it on my bench. Quite and easy job that, when I separated the gear box from the transfer box to halves of the 5th gear thrust washer fell out and it needed no further dismantling to change it. The only thing is his reversing lights don't work now, something fell out of or into the gearbox.

I repaired many a manual gear box, but with automatic considered it a specialised job. However my father-in-law had a Rover 3500 and the V8 engine had failed, and after repairing the V8, we found it had been towed off the motorway without removing the prop shaft, and so had wrecked the gear box, and father-in-law said price of new gear box means it's a write off, so will you have a go.

Well the first error was removing the box, I thought I could remove complete with torque converter, but it ended up with the torque converter staying on the flywheel, so a whole load of red ATF oil came out onto my chest and sprayed onto the drive, wife hears me yell, and comes out to see all the red viscous fluid running off me, and thought the worst.

However a good bath and I delved into the box, the plates had clearly worn, and were replaced, the bands seemed OK, and I rebuilt the box and replaced it in the car, crossed fingers, but it worked A1, and if anything easier than many of the manual boxes I had worked on, lost count of how many Landrover series II boxes I have done, and Massey Ferguson 2135 tractors, latter normally to repair the hydraulic pump, but each one was slightly different, and to be frank would not want to try to repair either of our main cars, 8 speed auto in wife's car, and 5 speed manual/auto with low ratio selection and auto bit selects 4 wheel drive when the ABS detects wheel spin. I think if the Sorento box goes I would scrap the car, and if Jag box goes cry, as god knows how much to repair that.

All I can say as an ex-mechanic is you must be very brave to attempt DIY repair.

You could and should have. Did you not undo the torque converter to flexplate(flywheel) bolts?

Surely you did not replace the gearbox with the torque converter still attached to the engine.

Yes did undo the plate, and reassembled in correct order.
