1HDFT & auto upgrade (1 Viewer)

[AJBRED]

I have a 2003 PC with a 1HZ. I looked at putting varous engines in it. In the end I have bought a 1HDFT and auto, I am not a huge fan of electronics so I stayed away from the 1HD-FTE. I have the engine installtion and upgrade in hand, ie intercooler, bearing check, turbo service/upgrade etc. Where I am struggling is the auto. I can't even identify it.

Can anyone help me

1) Figure out where to find any identification numbers on it?
2) What auto's these engines came with?

Lokking for help

PS on my PC I have 3rd door, internal and external water tanks and general long distance touring interior upgrades. Best thing I did was get rid of the dash bump pad on the passenger side and replace it with a tray with a cushion on the front edge so it is still safe but so much more useful.

That's an electronically controlled A442F with a HF2AV Tcase(full time, viscous coupled)

Sounds like a cool project ,
what intercooler setup will you run

brilliant. Thanks for the quick response. Do you know much about the electronic control? is there anywhere where I can find out what each of the electrical plugs do. I figure if I know this I can decide whether to try and use them or not. My understanding is even though it is an electronically controlled auto it will work as a STD auto without the electronics. So I was thinking if I could leave it pretty standard and then put some switches in to achieve some of it's options which I assume to be sport mode, decent mode etc it would be OK for my task which is a fairly utilitarian long range travel vehicle. Any thoughts?

Is you engine the electronically controlled version?

Thanks

Jeff

My other diesel is Massey Ferguson 135. But generally I prefer 2 stroke dirt bikes.

It is from NZ.http://www.4wdbits.co.nz/ProductImages/FullImage/intercooler80w.gif

It will have an electric fan on top. So I will have a bonnet bulge and an opening at either the front or the back for air flow. I will fit a dummy bulge to the car and then go for a drive with a U tube manometer attached to the front and back so I can figure out which provides more natural air pressure. Any thoughts?

I know a bit.
You need the EWD for the vehicle that the engine/tranny came out of, probably EWD272F which covers 96 up HDJ80.
I have been told the ECT type will work w/o computer hooked up, but you have to do all the shifting yourself with the stick. As I understand no signal from computer to shift solenoids = no shift.
I think you are going to run into some issues trying to fudge the tranny into working without the ECT computer and info from the TPS... but you never know till you try.

My 1HD-FT is non Electronic and non EGR motor..

What is a 2003 PC?

 

[AJBRED]

Ok thanks for the info. Given the engine I have is not electronic I assume if I get hold of the right EWD for this model engine and tranny combination it will just plug in and work. Does this sound correct? If it is then I just need to determine the exact EWD and then fit up a wiring harness. I am thinking if I get the right EWD getting the wiring harness will be difficult as I expect it would have been wired into the full car wiring harness. So getting just the parts/wires to go from the EWD to the Auto could be problematic. Any thoughts?

I came across this website whilst looking for solutions ( Wholesale Automatic Transmissions ). Their is a tech help column for Auto transmission issues. I read through past postings and it looks very impressive. I have sent them an email. I saw that the company had suipplied aftermarket electronic control units for auto's in the past so this may also be a solution. If you have not checked out the sight before it is definately worth a quick visit and read of Orto's replies.

A PC is a personnel carrier. I expect it is a Australian term. Here is a pic.

Toyota Troop Carrier (75 series) - Ultimate4WD Equipment

I also attached a pic of mine. Not usre if it worked.

I have 3 youg boys so it is ideal for beach and bush. Not too fancy. For instance I have taken out all the carpets and mats and painted it with 5mm thick polyurethane. They use it for lining the backs of utes (pickups) trays over here. It is as tough as nails. It cut out heaps of noise and means I can just sweep or hose it out.

Any thoughts on the auto would be appreciated.

For the engine I have a aftermarket intercooler. When I install I will fit the 3" exhaust. I will then try and get as much boost as I can without getting too high EGT's. Any thing you would recommend?

Regards

Jeff

No, an EWD is an Electrical Wiring Diagram manual.

It shows what all the wires and connections are for the whole truck, and therefore to the engine, so that you can wire it up correctly to your truck.

You would probably need the EWD for both the truck that the engine came out of, and the truck it is going in to, so that you can match up the wiring.

 

[AJBRED]

Ok Simon thanks for the reply. Your right I will need the wiring diagram for both to make it work. I have found that several places sell after market TCU's (Transission Control Units). So I may be able to just wire the engine to the original troopy loom. I suspect this will not be too hard as most of the sensors etc will be similar if not the same. I can then wire up the Auto completely independently to an aftermarket TCU. Alternatively if I can get hold of a toyota TCU for my new engine/auto combination then I will have to chase down the wiring loom connectors and wiring loom (or make my own loom by using the EWD's).

Your pic looks mighty cold. A bit different from Perth. Do you run an intercooler?

I really enjoy driving in on snow to go backcountry snowboarding.

No intercooler as yet, plan to go water to air at some stage, probably some sort of custom laminova setup.

 

[70sguy]

Does your troopy have a 5speed? H55F or?
Why not just swap in the 1HD-FT engine and not the auto tranny w/ Full time case?

 

[Clint79]

The troopy will have the r151 box

 

[70sguy]

Ooooo.. so much for that idea.

 

[AJBRED]

Not sure of the G-box number but it does have the standard 5sp that comes behind a 1HZ. So I'd say Clint has it right and it is a R151.

I was driving the car through regular traffic the other day. Not putting under any significant load or anything and when I went from 2nd to 3rd or 3rd to 4th it became stuck in no gear. I pulled over. I tried to get it to go in any gear so I could get the car off the road. Eventually I got a gear but it was reverse. SO I reversed into a less dangerous positiona nd started to try to fix it. Took the floor out, took the gear shift out. Still could not mave the gear selector arrangement to any different position. I had time so I then took th enext layer at the top of the gearbox off. STill could not shift the gear selector. But I did notice a large part of the aluminium housing had come adrift and was freewheeling around the output shaft (I think it was not too easy to see) It was at this stage that I thought 1) Time to organise a tow to get home 2) Better get the auto sorted behind the 1HDFT ASAP.

So thats where I am at. I was going to use the 1HZ and 5spd in an old HJ45 I have when I toiook it out of the troopy. It looks like I will have to do repairs before that happens now.

Either way the Auto behind the 1HDFT seems like the strongest and best option to be behind that engine.

Why do people not like the full time 4WD and the viscous diff?

if its the standard box behind the 75 1hz it could possibly be a h55f

Not very likely in a 2003 Troopy.

I see Queensland cruisers have useD ur pic in there add mate

 

[AJBRED]

I could not find it. Where was it?

True didnt realize it was a 03.

Clint, Yeah they did the buggers never even asked me either lol

 

[AJBRED]

Gents thanks for your help. I now know what auto it is and what transfer box it is. One more question if you can handle it.

Can the transfer be changed to part time and keep the viscous diff or can you give me a description of the viscous diff operation?

I am only used to the traditional transfer where you have hi and lo and no diff in the centre.
