Hi.

I am new to this forum having just recently bought my first Pajero. I have had a bit of bad luck latety so I hope someone can shed some light on my problem.

I have a K reg 2.5 Pajero Deisel with auto transmission which I bought back in March. It is in very good condition and ran perfectly until it shed its crank pully and came to a staggering halt.

I had the engine rebuilt and it run fine except it will not change in to top gear. It feels like it wants to but will not 'lock' in. The upshot of this is that I am running at 3k revs at only 50mph. To get to 65 I am nearing 4k. Needless to say I do not run above 50 mph at the moment in case I blow the enging by over revving.

Before the re build the gear change was perfect and it woul do 90 no probs within a safe rev range -- it never felt like it was straining -- but it does now.

I have read on this forum that the two sensors on the head at the front on passenger side may have been connected the wrong way round. The symptoms described by the writer were exactly like mine so I thought I was in luck. However, when I tried to swap them I found that the spade ends were two different sizes and one would not fit onto the other.

My question is this. When an engine is stripped for a rebuild, are these sensors removed and, if so, could they have been put back in the wrong holes.
Would they fit? Would the symptoms be the same as if the cables alone had been swapped.

I find it odd that it was perfect before the rebuild and is not afterward.

I took it to a auto box specialist who took it for a road test and declared that the seals had gone.
Is this possible even though it was working fine before.

Sorry for being so long winded.

I hope some one can advise.

Best wishes

Mack

First of all welcome to the forum. I'm sorry nobody has answered your question yet but don't be disillusioned we have read your thread and really can offer no immediate solution.

I tend to think that if the tranny worked before your engine work and it didn't after it must be something the mechanic did (or didin't) do and you should let him sort it out. Often a broken or misplaced wire will be all it takes to give you some strange results.

Hi Jim

Many thanks for the response.
Perhaps you are right, I should send it back to the mechanic and have done with it.

Best wishes

Hi,
Is the overdrive button switched on, if it is not you will not be able to reach fourth gear.

Hi

Yes, the overdrive button is on. I have tried it in both positions and it makes no difference.
