Thread: Overdrive??

If you search around a bit you'll find a few threads about LT95 overdrives and how they don't survive behind an Isuzu.

Yep, they struggle to survive behind a stock V8...

Roamerdrive don't make one for the LT95 but say they are working on one, but I don't think they are any closer than they were a year ago. I emailed them about it, but never got a response.

Only the 6wd would not be able to take a overdrive if ever one is manufactured as it will tack on to the rear of the LT95 Where as the PTO for the winch comes out the underneath.

Thanks Leigh

G'day Leigh, Some bad news mate, If your Perentie has a winch fitted as the above suggests, you cannot fit an overdrive to it even it you wanted to. Reason is as you hint, the winch PTO drive is from the gear on the rear of the mainshaft (in the transfer case). It is a special gear with teeth on it to drive the chain for the PTO. When you fit an overdrive you remove this gear and replace it with the overdrive gear. So you can either have a winch or an overdrive, but not both. I would stick with the winch personally but if you decide you want an overdrive I am certainly interested in buying the winch and PTO assembly from you.

I bought mine new and its been behind the 4BD1/ Lt95 since the 80,s.
Now turbo,d but is still going strong.
Synchro when changing down is dodgy now but I just double d clutch.
I dont have it in OD when working hard and slip it out going up hills.

Didiman, there is a lot to be said for mechanical sympathy ;-)

Yes there have a few people who have had the overdrive survive behind an Isuzu but the majority have the opposite experience. To me it is clear that the overdrive is living on the edge and driving style depends on whether it lives or dies.

At 100 km/h, an Isuzu powered 110 with the standard transfer gearing of 0.996 and 31" tyres is only turning 2370 rpm in 4th gear. This is quite tall - 4th in these things is similar to 5th in most vehicles. IMHO, a n/a vehicle does not need an o/d and would struggle.
