Thread: Perentie gearbox issues

My experience is the LT95 tends to be sticky coming out of gear, but only when cold - which it hardly is at present in Adelaide. And this symptom disappears with Syntrans.

I would be looking more carefully at whether the clutch is still dragging - check the pedal free play, but also check that there is not oil leaking onto the clutch (probably from the pump on the front of the gearbox, from the rear main seal, or both) by removing the wading plug on the clutch housing. While a lot of oil will make it slip, a little may cause it to drag. (Not an expensive repair - except that it involves removing either the box or the engine!)

Ok ill have a more thorough look at it tomorrow the only thing is the hard top feels almost the same now with regards to being a bit sticky but i haven't put the syntrax in hardtop yet but would normally find it strange that two trucks would have the same problem with same symptoms at the same time that's why i put it down to the box just being a bit sticky but im probably completely wrong hmm ?? the 6x6 though is absolutely beautiful and much nicer to drive than the 4x4's but i put this down to it being a 1997 and not an 89

Isuzu upgraded the 4BD1 and 4BD1T late in 88, but AFAIK the NA engine used in the 4x4 was the same earlier engine after 88, but the 6x6 used the update engine.

Others here on this forum rebuild the LT95 to a high standard, though for considerably more.
Perhaps (with all due respect) you get what you pay for in this instance?

full marks for looking after your mates, but an LT95 is a simple box.
of the 5 LT95 boxs in SA as well as 2 LT85s all sitting behind turbos, one with now 180k on it none have had any problems, and yes thay use Timkem bearings. how you can justfy 4K for a rebuld is a joke

Alright turns out my old man knows an ex mechanic from the adf (his company does a lot of contract work for the adf) so he's going to come up and have a look at the trucks on the weekend, check it all out and get it all sorted for me so been pretty lucky there.

I agree with getting what you pay for and i think it applies for most things in life but there is a difference between that and getting taken for a ride. I've been ringing around Australia over the last few weeks, getting various prices on various things and have came to the conclusion that due to there being a limited number of workshops familiar and willing to work on these trucks, they are going to rape you for every last dollar they can IMO and same goes for parts until the spares come up or auction at least. A guy ebay wants $300 for a mirror arm hahaha A MIRROR ARM.

Well if it is the 6x6 mirror arm you are after, the long arms are also made by Britpart, plenty of Aussie stockists of that brand around...

My first gearbox rebuild cost $4500, though I was younger and slightly dumber back then, just had some more work done on the transfer by a better source, and it wasn't cheap either. Having read the receipts for the first rebuild, I can see why there is easily over a grand in parts alone. Priced a main shaft or gear cluster lately? How about the taper roller bearings? All depends what wears...

I'm looking forward to picking up a few Perenties on ebay or gumtree after the owner gets the bill shock from fixing something they didn't research before purchasing...

I have no doubt parts are expensive for an old obsolete box but that doesn't justify the the cost of labour going up by so much I mean its just a normal gearbox, its not some space age CVT box that no one knows how to work on and when you can buy a low km puma engine, transmission and transfer case with everything on it for around $5000 out of the uk it seems a bit silly to me unless I'm missing something. Before i bought it i did research into replacement engines, parts most things i thought i'd need and as my business regularly bring half full containers in from the uk i thought if i need anything i will just update the perentie with new gear. But then hoped on here and everyone raves about the 4bd1 and LT95 combo and i did a 180 and thought nah ill keep it the way it is, also fell in love with the noise and rattle and the look on peoples faces when they come for a drive haha.

Also if anyone needs anything from the UK yell out and i will see if i can help out with shipping.

since buying my perentie in August- the gear stick broke right at the ball, clutch master cylinder leaked badly, and the oil had water in it. A bit dodgy for a vehicle sold with a blue slip. Changed oil with engine oil, replaced clutch mc and replaced gearstick, fantastic vehicle, I have already travelled over 10 000 k's.
