Dane Wilson's 5 speed conversion info

Below is additional transmission information that forum member Dane Wilson wrote up on his conversion of a non-recommended W58 transmission for use with the HVDA kit. Dane found that by changing the shift lever housing to a different part that the transmission fit the HVDA kit with no problem. This was his experience but you're on your own with regard to what HVDA recommends.

I have recently taken on the project of changing out my TR-6 4 speed w/ A-type, to a Toyota W58 Transmission... I wanted to share some experience with the community before you consider taking on such a project and know beforehand what to look for and expect...

In truth there are about 8 different variations of this transmission with a few of the more popular styles listed here: 

As you can see there are several different placements of the shifter assembly. When using Hermans (HVDA) conversion kit it is important you try to locate the one closest to the left which is out af an 82-85 Toyota Cellica (Supra) with the ma61 (Mk II) chassis... These are becoming incredibly rare and those that DO exist in most cases have an excess of 150k+ miles on them. The more modern versions will fit but require some alteration as you can see later in this post.

With the cover off you can clearly see what Toyota refers to as the [shift lever housing] which is where the units vary over the years.
The red arrow is pointing to the correct Shift Lever Housing.

Unfortunately I didn't know this information prior to picking up a W58 on e-bay... My transmission was out of a 87 (Mk III) Supra...
My shifter assembly looks like this:

And with cover removed the red arrow is pointing at a totally different shift lever housing. It positions the shifter way too far back.

Here in lies the dilemma... Just to keep in mind everything else fits... the bell housing connection, all the other supplied parts are ok... it is the Shift lever housing that is the issue...

There are several solutions to this...

1. Adapt the transmission but use the toyota shifter components
Problem: Doing this sets back the shifter position about 2-3" requiring custom interior work as well as the shifter being located in an uncomfortable position.

2. Get another transmission (sucks but it is a solution)

3. Fabricate (or cut/weld) the existing shift lever housing to the correct position.
Problem: This is a forged steel lever, you really need to make sure you do this correctly or it could result in failure.

4. (What I am doing) Toyota can order the shift lever housing you need it is Part number: 33502-14100. Unfortunately this little piece is $135 and you need to remover the tail housing of the transmission so factor in another $30 for the 04331-20050 gasket set.

Transmission: $100 Ebay
Shipping: $100 from LA to NY
HVDA Transmission kit: $1767 (price is going up soon)
HVDA supplied LUK Clutch Pressure Plate: $107
Shipping from CA to NY: $66

Add on top of that the part I need $135 +$30(gaskets) you can see this is not a cheap project. Especially when you do not factor in things like these extra parts.

For those of you not familiar with or new to the community Bob Danielson's Webpage should be bookmarked as it is so painstakingly detailed all the work he has put into his car with great "tutorial" and "how to's"

Feel free to ask if you have any questions or would like more info.

This is about 2 weeks worth of collective research after finding out I had the wrong shift lever housing.
Installing the newer Shift Lever Housing (Toyota part number 33502-14100) was a breeze and didn't even have to take the entire tail housing off... just slid it back about 2-3 inches enough to swap the shift levers...
This allows people to use any W58 Supra Transmission up to 92'.
