Philia_Bear sounds like a dead ABS module that needs to be re-soldered TCM issues.... I will let others comment on
Sylvia To many faults at once ! If your speedometer still works - I also think it would be the ABS module faulty - as this controls all your sensors and more. It could give you all those faulty readings... You can get new refurbished once.

Max Hi N.G, I'm newish here and this's what has happened with our '70' re the ABS/TRACS. The lights come on occasionally when one goes round a roundabout or over a bump. At it's last extensive service we got no fault codes. The mechanic said it was alright and perhaps a loose transistor on the ABS module that does all the 'thinking'. Unfortunately the module has to come out to be sent away for a refurbished one. A new one is a lot of money. Re your EGS 50-42 situation, I can't help here at all. 332 Converter lockup solenoid valve - Open Circuit, This sounds like the switch that makes the cars top gears 'lock in' to save fuel, is not working. When you give it some stick it doesn't respond as it used to. I hope this can elucidate you on some of the workings of your problem.
Ex850R Refurbished abs units are usually in stock at Berry Motor Group, they have them done by local and are reasonably priced. I got my last one from Midwest Abs, they did me great service! Sent a refurbed nice looking one with me sending mine back or bit extra for not. Berry's are cheaper nowadays.
