RE: W114 engine help needed.
The trans torque convertor hgas a plug with I think,a 5mm allen screw in it ,undo that and empty the convertor of all the fluid.to check a convertor is really a skilled job,but i find if there is a noise,any noise, it's time for a change.to check a convertor,lay it on the benck with the in put drive tang upper most.grip the inner drive with a pair of pliers ,gently so you don't mark it,then flick it backwards and forwards,it should be silent,any noise means it's shot.
To flush the lines,put a hose on one line,from the trans end and rig up a funnel so you can pour petrol in to the line,blow it through with compressed air.Or if you can hire one ,get a trans flushing gun.Petrol is what MB reccomend.The vacuum modulator is on the rear of the trans with a plastic line running into it from the intake manifold.It looks like a 50mm dia tin thing screwed to the passenger side of the trans.the linkage for the floor change fits the column change bracket.You can see it has a bunch of different holes.
to adjust,you place the floor lever in nuetral,on the trans you place the bracket,which is also hooked to the lockout switch,in nuetral,if you look close there is a hole which lines up,it's 5mm ithink.when the hole in the bracket lines with the hole in the switch,you place a drill bit in it,then adjust the length of the shift rod connected to the lever to fit.Make sure those little white bushes are in good nick.
flushing the trans just involves pulling the pan and cleaning it,buy a new filter,theyre cheap and most mercs of that era had the same filter any way.[:)]
The throttle posistion link if it has one,will be connected to the aclerator linkage,if it's a vacuum job there will be another line running to the trans via valve connected to the intake.Both systems must be in good order to prevent slip.[;)]
before you bolt it together,replace the convertor seal in the front pump,it can really give you irrits if the trans starts leaking after you just reinstalled it.[:(!][:)]
