The six speed auto is similar with 'active select'.

Would it be able to withhold more power than the 5 Speed?

Professional rebuilders can’t even guarantee a stock rebuild will last more than a couple of years as the 5L40E is difficult to rebuild reliably. Just ask @Fu Manchu who had an expensive rebuild grenade itself again in short order.

A 5L40E is the worst possible Commodore automatic transmission that you could take to the track. Either run it into the ground and buy something else to track or keep the track car so you’ve got a spare 5L40E for when the one in your daily driver craps itself because 5L40Es are rare as rocking horse shite and expensive to rebuild.

Also the torque converter clutch is a wear item and will destroy the transmission so best to replace that if it’s not been done before. I found that out the hard way on my old SV6 when the transmission decided to have a glitter party and eventually stop working.

Ah, I prefer to keep the car as long as possible as I’ve done a fair bit already but would there be any other auto transmission i can swap it out for?

OP isn’t after a manual trans, only automatic.

That is the six speed auto.

That is the six speed auto.

The 6 speed auto is a 6L50E made by GM. The manual transmission is an Aisin.

The auto is a 6L50 for a v6.
The Aisian is a 6 speed manual for the v6.
