I have list of Trimatic auto  transmission for 4 cylinder Toranas, but with two exceptions. I assume the HB Torana used a Borg Warner or similar and I can't find any model listing for the TA Torana. I assume the TA is the same as the LJ series and would have used a Trimatic "HL" for the 1300 engine and a Trimatic ""HY" for the 1760 engine.

 

I assume the rebuild costs for Trimatic transmission are similar regardless of the model.

 

Regards from Mike in Melbourne.

Gemini and Corolla also ran Trimatics. Google Button plan. There was probably others.

The Button plan was put forward in 1985. Toyota sharing autos (& engines) with GMH in the 1970s was just using good financial sense, to help increase local content. The local content thing for Aussie built cars goes back to the 1960s.

 

Toyota Crowns using GMH banjo rear axles was another example.

Yes, the HB had the Borg Warner 35 as its auto.

 

The TA had the same Trimatics as late LJ 4-cyl cars. The early LJ 4-cyls had LC type 1 Trimatics with the cable kick down. Probably to get rid of unsold units left over from LC production.

You’ll find them in Brazil, South Africa and other GM export countries. They were even made with Chevrolet pattern bellhousings to suit 6cyl Chevrolet design engines and another pattern to suit 4cyl engines. They were in the Opel Rekord which was made is South Africa as a Ranger and Brazil as an Opala. Some of these will be TH180 boxes from Strasburg but some were GMH Trimatic. From memory Rover and Fiat used them too. Dave Smith sent me pictures a while back of some weirdo boxes with Chev pattern and other bellhousings and they are both GMH. The odd bellhousing example was an electric kick down Trimatics. Both bellhousings have HOLDEN cast into them with a GMH part number on it.

Any info on the overdrive option? Think it may have been in Rovers.

It’s called a 4L30E. Used in Isuzu and other lower power vehicles. Google it and you’ll see pictures, you can see the old TH180 case in it. I think BMW used it too. There was supposedly a TH180C too, which is a light duty version of a TH350C which means it was basically a Trimatic with lockup converter.

Thanks Byron. They look longer/bulkier. Or is that the transfer case? Being low output specification I suppose they wouldn’t be up to duty behind an occasionally hard driven mild blue 202, say 120kw at the flywheel?

Perfect for that application, that is the definition of light duty!

That one is pure Trimatic, just the transfer adapter makes it look bigger. The 4L30E look like they have an extra transmission part with its own pan in front of the old TH180/Trimatic case. Probably would be hard to adapt to a Holden unless the nose where the bellhousing goes replicates the front of the TH180/3L30/Trimatic case. You’d be far better off with a 4L60 or 4L60E off a V6 and make it fit ( which is already done for you, see link). Here is some images:

Yes, just thinking of a possible alternative to the VN TH700R as I have heard of dramas with the conversion. I know they did come in a column shift configuration. I've heard the Triassic is more efficient and better suited to the lower powered application.

Oh Triassic, good one Samsung auto correct wtf.........

I’d not use a TH700. Get a later 4L60E which will be almost free and buy a transmission ECU for it. You might have to fiddle a fraction to get a speedo drive, although I think VR still have a speedo drive on them.
The trick with those spacer plates is to create a better spacer between the converter and the flex plate. Best idea is to weld the spacer to the converter tabs. Although this one appears to replace the original sandwich plate so probably only means 10mm spacers. Although depending upon how the converter matches up hole wise it may not need any.
I’ve seen a VN 4L60 adapted with a crossover linkage to a HZ, but I wouldn’t bother. You can buy push button shifters like in the attached link and also column cable conversions.

Trying to get tv cable setup correctly on th700 be major pita.

 

4l60e probably easier to get right although to that extent I'd wonder if could just go efi with vr ecu/loom with custom memcal.

 

Trimatics can be built well with lots of interchangeable parts for improvements as long as go right trans builder...love the one that was in my 355 sle which I still can't find damn 7 tooth gear to correct speedo lol

I did see a VK EFI engine in a Landrover controlled with a VN ECU. If that can be done then a VR auto ECU would work the same and would do the transmission as well. Easy to do if you mod the ECU with an EEPROM or similar memory so you can tune on the run. Or buy an aftermarket ECU.
