Shudder and Stop

[knockmacool]

This morning I visited the Blarney Golf Resort. The MB Club UK has organized an excellent Irish tour and Blarney has been their base for the first 4 days. Participants were mainly Irish, British and Germans. There was a fellow American as well! As for the cars, three amazing Pontons travelled from Germany and there were two Irish based 113s. The Pagoda drivers were Eamon Corrigan and Charles and Moira (?),  who I had spotted driving down from Dublin on Thursday. It was great to meet them and I picked up some pointers just by comparing cars. I followed the convoy into Cork City and decided to meet up with my wife. This is when my problem started (no, not with Anne )

I parked up and when we restarted the car uphill two minutes later it shuddered and stopped, engine still running. It's like someone applied the brakes. I put it in park and then back in Drive, but nothing, and it didn't even roll downhill in neutral. It did however work in reverse. Parked up and called AA. By the time they arrived could not reproduce the problem. Trans fluid at normal levels, but do notice clunk into drive or reverse. Did drive car thirty miles home (AA kindly followed first five miles), without problem. What should I be looking at? Car is a RHD 66 auto, and I recently replaced bushings etc for gear selector. It does go up (and down) the gears very smoothly except first changes up when it seems to over-run. Will check rear axle fluid level of course, but would welcome suggestions as to what we should troubleshoot.

Sorry to hear about the trouble. I wonder if it has to do with your neutral safety cable gizmo? I can never think of it's proper name but it's on the firewall by brake booster (LHD).

You might want to look at the drive shaft.
The engine will be able to apply maximum torque in reverse so I'm not surprised you could get it to move in that gear but not in drive where it starts in second gear. The shuddering kind of indicates something out of balance like a broken flex disc.

Could be something else entirely but it's a place to start.

Also check transmission fluid cooling pipes for crimps and kinks.

Gents, thanks for the guidance. On the to do list for the weekend. Did check the flex disk when we did the gear linkages, but will check again

Checked brakes- OK. Since it happened after I turned uphill from a standing start we thought rear diff, but Dave insists we would still  "hear" the problem. A little low on fluid so topped it up.
These things come back and bite you sooner or later, but don't know what else to do...

If it happens again, pop the hood and check the brake booster actuating shaft. pull back on the actuator. If it travels back, it means the pivot lever is hanging up.The fix is to pull the booster and check pin at the bottom of the pivot lever.  Cheers
