R154 Gearbox

Turbosupras Review On  Toyota R154 Gearbox.

The R154 is a standard 5-speed transmission, with 5 forward gear plus reverse. The factor for the toughness of the transmission appears to see also by the nude eye. The exterior housing and also the equipment themselves are credibly sized for a performance-oriented transmission.

Toyota R154 Quality

As with a lot of Toyota driveline elements, the R154  has  high performance and genuine quality.

As consistently appears to be the situation with contemporary innovation, there is consistently an Achilles heal.

The weak factor, however, is the first gear thrust washer. Being of an actors design, this component is vulnerable to failing if the box is abused.

  • misuse or abuse of the transmission
  • When the transmission is utilized with a high-clamp and/or switch clutch,

The simplest repair for this weak point is to brighten on the transmission and also treat it with regard. For transmission proprietors with much less self-discipline, the most effective alternative is to have actually the transmission damaged down as well as rebuilded with a brand-new drive washer made from chromoly for extra stamina.

The turbosupras team checked the price of its part. Price is  affordable, and its around AUD$ 26.50. However the damage it can cause in the event of failure is quite humbling. Nonetheless the harm it could create in case of failing is fairly humbling. The initial equipment bearing takes the burden of this failing as a result of being situated before the drive washing machine.

 

In an ideal globe the suitable remedy is to change the R154 with a V16x transmission from a Mk4 Supra. These are a lot more powerful as well as much more commonly confirmed behind big-horsepower 2JZ engine mixes.

In much more extreme failings, or if the auto remains to be driven after a failing, several of the equipments will certainly have to be changed. Equipment alone has actually been valued at AUD$ 550. Not a low-cost workout, as well as one far better stayed clear of.
