They are an identical plug & play fit.

 

The speedometer sensor may be geared slightly differently if UK auto has a different diff ratio?

 

But almost nobody runs on stock rims and tyres, which means that almost all are running slightly out of kilter.

 

They change hands for £150 to £200, depending on how many miles it has done.

J spec is A340E and U.K. spec is A343E.

 

A later model box is likely to have upgrades, but I have seen no information to confirm this?

 

However, Mr T. uses different codes than are used by AisinAW who manufacture these boxes.

 

According to Mr T, both N/A and J spec T.T. boxes are A340E, however, these boxes are very different.

I don't think it's to do with the age, but probably more likely to to do with the market place it was sold to. Like all the other higher spec'd parts on the UK and Euro specs, so they would be better equipped for the harder/faster driving conditions the car would be capable of being used for.

 

So it's logical that the UK auto box could well be stronger than it's j-spec brother.

J spec Supra N/A & T.T. are both A340E. (Sub coded A340E-GE & A340E-GTE) (US & Euro spec T.T. will be A343E-GTE)

 

Soarer (& others) are A341E

 

Early LS400 (& others) are A342E

 

Later LS400 (& others) are A343E

 

The Tiptronic box, which is last in the 35000 series, is coded by AisinAW as A30-40LS. Mr T called this one A34#E, but translated from Aisin to Toyota lingo as others, would become A340S. Which contradicts any assumption of larger numbers denoting stronger boxes, because the Tiptronic box is the strongest of the lot.

Should you find any information other than Old Wives Tales re. "strength" of these variants, please let us know?
