nothing to do with transmission oil levels It has everything to do with the clutch operation not fully disengaging possible air in system, problem clutch master cylinder if the system has not had replacement slave and master cylinder since new , replace with new items other more serious problems include clutch plate linings , oil/ grease on linings and spigot bearing / bush seizing on the gear box input shaft and not allowing the shaft to stop spinning when the clutch is disengaged Tests are simple if when using the clutch , there is no shuddering, slipping etc then the plate is eliminated as a problem and that leaves the spigot bush/ bearing the fix here is the box out and clutch removal so do the hydraulic system first as it is the cheapest

The inside, large pin, that pushes out to the hydroboost, may have fallen out when you took off the booster. Also the pin from the booster to the master cylinder may have been stuck inside the hydroboost that you took out. Pull the master cylinder off. You will see that the large shaft/pin is missing. Good luck.

comes up as a 4x4 if high millage on the transmission suspect internal wear do these checks check oil levels service and replace filter if oil has burnt smell or brown have solenoids tested check the engine /gearbox mounts check transfer box condition check over what is fitted to your drive train the drive shafts /CV joints, live axles universal joints check back lash in diffs

Do you need the engine harness, dash harness.? where is your problem?

The wire feeding the front left turn signal is likely crimped or stretched and touching the body somewhere. Do you best to trace the left front turnsignal wire back as far as you can - even just jiggling it might give you short term solution (although it will probably come back). The fast flash of the rear light is because the short up front is letting too much electricity run through the flasher module. This makes it run too fast. Find the short up front, and both problems will be solved.

shift when transmission is in nuetral

sounds like u got a clogged fuel filter, or you have got a fuel line somewhere that is sucking air in, could be anywhere from the pump back to the tank, if that shows no luck, get a piece of clear hose and put that just before the pump and look for bubbles, the slightest of bubbles will cause it do run rough and stall failing this and there is no air bubbles i would say your injector pump needs rebuilding but this is rather unlikely unless u have got a fair few miles on ithope this helps

Check in the fuse box for any charging relay.

We do not have this diagram, sorry.

the electronic sender will have to be connected to stop your problem , it will have to be in place with the manual guage. it is behind intake, under fuel filter.

check ecu1 , ecu2, ecu3 fuses under hood.

Here is the diagram. The white circle in the distributor cap is number one plug wire location, rotoation is clockwise

you can try changing the filter, but more then likely you will have to drain the tank, as water is heavier then fuel so it will be on the bottom of the tank. Good Luck Tim
