300CE, 1990 Diagnostic Help

[mudditt]

When pulling away at about 20mph, transmission dropped to 2nd, very loud bang.

Speedo to max, rev counter to max.

Gearbox is auto.

Any ideas ?

Forgot to say that there is no drive to the rear wheels now

Ugh. Sounds like something broke! Check the flex disk, you might be lucky and have sheared it off, but usually you get some warning there.

Otherwise, I'd suspect a broken clutch drum in the tranny or sheared bolts on the torque converter. Could even be the main shaft in the tranny, but for sure if it's not a flex disk, it's tranny time!

Small outside chance you have a broken rear axle or diff, too -- does the driveshaft turn independent of the wheels?

Thanks Fred

Turns out the prop shaft sheared (according to dealer....phew)
