FAQs

What is the difference between R154 and W58? ›

The R154 is much more valuable compared to the W58, mainly due to its reputation for being able to handle a lot more power and generally having better gear ratios compared to the smaller and lighter W58 trans.

The W58 is a great transmission. It shifts real smooth, and can hold decent power. In Australia a lot of people convert their v8 soarers to 5-sp and all prefer the w58 over the r154. My response is not in any way to flame aka paco's, but he did say "in my opinion".

W58 uses a push type.

rebuilt with 2-3 performance parts from Marlin Crawler (like 1st gear thrust washer, bearing retainer,etc.,) can take you up to 1000 whp.

There are plenty of sites that have the gearbox ratios for the w5x series, the w57 and w58 have the same first 4 gears as the same ratio, but fifth is different (w57 = 0.86 and w58 - 0.783)* This is how we are going to verify a w58.

The W58 was 15.6 inches (400 mm) in diameter and 40.3 inches (1,020 mm) long, and weighed 257 pounds (117 kg). The yield was 200 kilotonnes of TNT (840 TJ). The warhead used the Kinglet primary, which it shared with the W55 and W47 warheads.

This transmission is popular as a replacement for weak stock transmissions in other vehicles. It came in two varieties: the original found in the 1982–1989 non-turbo Supras, Celicas and Cressidas of the early 1980s; and the later version found in Mk3, Mk 4 Supras and Lexus SC 300s.

The powerglide and TH400 are often used as the standard for durability in competitive drag racing. There are applications where the powerglide is better used, and certain cases where the TH400 is more suited.

In the hands of a competent driver, the 4- or 5-speed still offers, in most cases, the quickest way down the track.

Pushing & pulling guidelines. As a general guide, push where possible and pull an object where it is not possible to push. Don't bend over at your waist- keep your back straight.

Is the push pull method the best for steering control? ›

Overall, the push/pull steering technique is a valuable skill for any driver to learn. Its benefits, including greater control, reduced strain, and more efficient movements, make it a preferable method to hand-over-hand steering.

Pulling stresses your shoulders and back. You should push hand trucks, carts and other loads. Pushing a load is safer because: ✓ You can see where you are going. ✓ You can use your body weight and larger muscles.

The Supra's engine is only rated at 335 horsepower (although dyno testing has shown that figure is actually closer to 400 hp), but Papadakis found the engine to be far more stout than its factory rating would suggest. In fact, he believes the stock internals are capable of handling as much as 1,000 horses.

R154. This is a 5-speed transmission found in the MKIII Supra Turbo, Toyota Crown, Toyota Chaser Tourer V, Toyota Mark II Tourer V, Toyota Cresta Tourer V, and Toyota Soarer (turbo).

Although there are no official torque ratings for this transmission, it has proven reliable in cars with over 1000 whp, which is more than enough strength for the average motor swap. Consequently, those looking for an alternative 6-speed for their LS swap should look no further.

The W58 & W57 share the highest gearing and closest ratios (1st, 2nd, 3rd, and 4th (direct)) of the stock W-Series transmissions. The ratio shift was accomplished by taking the W55 base ratios and changing the input shaft to intermediate shaft ratio by 7.9%, thus shifting 1, 2, 3 ratios higher by that amount.

R154. This is a 5-speed transmission found in the MKIII Supra Turbo, Toyota Crown, Toyota Chaser Tourer V, Toyota Mark II Tourer V, Toyota Cresta Tourer V, and Toyota Soarer (turbo).

The easiest way to distinguish between the two designs is that the 6R60/6R75 stator support has a front bushing, whereas the 6R80 does not and the 6R80 bore is larger.

The W55 is normally regarded as being a wide-ratio transmission. The overdrive is also relatively short, only reducing highway revs by 15% First Gear: 3.566:1.
