torque lockup question

[Tractorat]

This is probably a pretty stupid question. But will the torque converter lockup in 1st or 2nd ? Or does it have to be in 3rd to lockup ?



Thanks,

Probably not in 1st. Mine will lockup in 2nd & above with DTT transmission.

not by its self. with a switch it will lock in second.

48re locks up in 1st 2nd 3rd and 4th with a mystery switch

Thanks for the reply. Im not sure what a "mystery switch" is. Will a stock 48re lock up in 1st and 2nd by itself ? Or does it need the "mystery switch" ? Is the mystery switch a kit that I can buy, or just something that is wired in ?



Thanks,

The torque converter in my '03 with a 48RE locks up in second gear if it is manually shifted into second gear, but not first gear. It locks up in third gear if the "O/D Off" button is used.

I have a stock 2002. It locks in 3rd and 4th only in stock trim. One reason that we can't have exhaust brakes without Mystery switch or modding the trans.
