SHIFTER POSITION HOMEWORK - Internal link is available in 4 positions A-18' B-19' C-20.1/2' D-21'
Volvo 240-The 'Dellow' kit-'Volvo 4 cylinder to Supra, tilted engine', specify shifter in the 20 1/2' position
Volvo 740/940 models - For 740/940 they use the same bellhousing as a 240, but there is a shifter length problem and a solution. Problem: Compared to a 240, the 740/940 gear lever (and driver's seat) position is located an additional 4' (101mm) further rearward relative to the engine/gearbox. The Supra gearbox has an internal gearshift linkup with a choice of gearshift positions but doesn't extend far enough back as required.The longest Supra shifter option is 21', so for a 740/940 even if you select 21' your still 3 1/2' short of the original chassis hole. Measurements are from start of gearbox (not bellhousing) to centre line of shifter. Solution:- Hal Glenn from the USA overcame the fittment issue by extending the Supra internal linkage and alloy shifter box.
UPDATE 2007 - Dellow have limited stock of a 'Long stick Supra version' that would fit a 740.
W58 steel center plate 89+ MK3/MK4 supra, SC300. This version is considered stronger due to wider bearings and gears, different gear selection mechanism.

Thought we could start a thread on the Toyota gearboxes.W58 Gearbox Strength
Jan 25, 2012 Anecdotal evidence suggest the W58 is OK at roughly stock TT power output if you don't launch it hard, but not much more. I don't know about the torque: that's important because it's probably excessive torque that kills most gearboxes and not excessive power.
The W-range of gearboxes were available as 4-speeds(W40, W42, W45) and 5-speeds (W50, W51, W52, W55, W56, W57, W58, W59).
The W40 to W45, and W50 to W52, are earlier designs, and have steel front casings.

The W55 to W58, are all essentially the same gearbox, parts and bellhousing interchange(but not with the earlier versions), it has an aluminium front case, but each model have different ratio sets. It is these models that are commonly referred to as the “21R”/”22R” or Cressida gearbox in South Africa. These gearboxes were used locally in Cressida, Hilux, Hi-Ace, Stallion, Venture, etc models, but with different tail housings/gear lever locations.
When you are at a scrapyard, or importer, all of these W55 – W58 models gets referred to as a “21R” or Cressida gearbox. But in reality no 21R gearbox exists, 21R is a Toyota engine code for the 2.0L(21R) SOHC engine used in the 70s/80s Cressida. So in effect it is the 21R’s gearbox. Which was most likely a W40 or W50.
Externally all these W55-W58 models, look virtually identical, and it’s very difficult to make a positive identification, without opening it up and doing a gear tooth count. Member KSF wrote “From the outside the 2l and 3l boxes are identical (expect if the bellhousing is still on). You have to check 3rd gear ratio (1.26 for 3l, 1.35 for 2l) to find out which it is, or lift the lid and count the teeth on the input gear (2l 18, 3l 19). They share many parts, in fact all, except the input, cluster and 5th gears. Mainshaft & gears and selectors are identical.”
Of the W-range, the W58, is supposedly the strongest variant, as it had a steel sandwich plate between the centre and tail housing sections of the gearbox(whereas lesser variants has an aluminium sandwich plate), and would most likely have been fitted to 2.8L(5MGE) and 3.0L(7MGE) Cressida’s, and the Celica Supra sold in South Africa. Although the official torque rating does not reflect it, this gearbox have been known to withstand 400HP.

The R-range of gearboxes, is sometimes referred to as the Supra gearbox in SA, or Fatboy, or sometimes KZ gearbox(as it was used with the turbodiesel 3.0L KZ-TE and 3.0L D4D, both in 4x2 and 4x4 applications). The R-range, is stronger and somewhat larger than the W-range of gearboxes.
But the “Supra” designation is confusing, as different models of Supra used different models of transmissions.
The R154 variant, was used in conjunction with turbocharged 6-cylinder petrol engines(1JZ-GTE) in coupes and sedans, and as such as a high first gear, and ideally suited for use in “lighter” bodied vehicles, but is very scarce in SA.
Most other R-range variants(R150, R150F, R151F, R155, R155F, R156, R156F) was designed for use in LDV’s and SUV’s in conjunction with turbodiesel engines(high torque), and as such has a lower first gear, better suited for heavy vehicles. Although the official torque rating does not reflect it, this gearbox have been known to withstand 600HP.

BTW Aisin Seiki Corporation, like Borg-Warner, Getrag and ZF, manufactures gearboxes for various vehicle manufacturers, not only Toyota.
