Model is: DELICA Spacegear,1996,auto,2.8l,120.000km during a rather soft acceleration around 85-95km/h speed the computer regulated automatic gearbox shifts up and down every second or so. this happens not all the time but often enough do be annoying. the comp.diagnosis system at a mitsi dealer indicated a fault with the LPS sensor which is a little electronic box fitted near or on top of the injection pump? It would be a commen thing. The problem is the $ 575.- plus work quota and the info this may not even fix the problem!!! is there an other possible reason for that fault and a cheaper solution or a cheaper spare part? the mitsi part no is:M*JCMD620874 and the engine is a 4M40 same as in Pajero the mechanic said used ones would be worn.

    as i just bought the car 3 weeks ago i haven`t found out all the variations of the problem yet but what i have noticed is that it seems to happen also at other (lower) gear change speeds and that i can prevent it by switching off the overdrive at the price of high rpm and diesel consumption - not a good solution.

  • rony_nz Jul 29, 2009

    thanks for your suggestion but that`s not much different from switching the OD off = higher consumption and higher wear & tear but most of all i`m not boyracer i prefer to go smooth (: , but has anybody tried to use a used LPS with success? and again why was i told that the change of the LPS sensor may not even sort the problem - so what else could it be. it must have to do with the control of the auto gearbox. is there a hidden auto-gearbox-specialist out there?

It's a fault with the solenoid that controls the gear change..You will need to replace it and I would suggest you look for the part on ebay..This will be the cheapest solution.

Switch ‘PWR’ on. To turn it on use the A/T switch to force the
gearbox to a 'power' mode: faster acceleration by going to higher revs before
changing up a gear.

Cant help on this one iam afraid ,i dont know of a cheap quick fix other than to go with the dealer on this one ,but i would get a second opinion from a auto specialist .A lot of newer cars are like this and its one way to put general garages out of business especialy with new cars and encrypted software that can only be diagnosed over the internet .Sorry i just cant advise other than if vehicle is over 10 yrs old then trade it in for the buy back being offered in various countries against a new vehicle to help the motor industry

MY delica spacegear wont shift to higher gear

delica spacegear secret year and secret country and no engine told

what year,what engine ,35engines used world wide all years.
see how years matter, most> all books are by years. see?

1968 to present no non deity can guess.this ever.

there are 2 causes
bad engine (weak) or bad transmission not told.
if RPM of engine rises good but not MPH that means bad trans
if RPM is low only and weak that is a weak engine
we check all fuses
then we scan the PCM in USA 1996 up all all OBD2 scan tools work
and it tells you things bad, called DTC errors

really no car told

Hi I have a 94 mitsubishi delica.The o/d button doesn't work. I was told this is a regulation that o/d is always on.My o/d only works if I pull the fuse.That itself causes problems.Any ideas please.

TCC solenoid could bad or the button could be bad, or the ECM could be bad, along with wiring. when you pull the fuse the transmission shifts with pressure. Hard shifts at higher RPM's. Needs to be scanned( which does't do to much) and checked with a volt/ohm meter. Since it still goes to OD, Your transmission is still working. You have an electrical issue.
