1971-1977 Vega LS Trans Mount Adapters

Planning a late model GM gearbox behind the LS in your 1971-1977 Chevy Vega? These are the four BRP transmission mount adapters. Two are for TR-6060 six speed manuals and two are for 6L90E, 8L90E and 10L90E automatics, so the transmission can sit on a traditional mount.

Two manual, two automatic adapters
Both TR-6060 adapters ship with hardware

The BRP install guides page does not list a Vega guide, so this page sticks to what the adapter listings say. For mounts, manifolds and fuel parts, go back to the 1971-1977 Vega LS swap parts.

1971-1977 Vega fitment notes

No BRP guide covers the Vega, so tunnel and crossmember fit for these gearboxes is not confirmed here.
BRP lists both automatic adapters for use with its own transmission crossmembers.
An MG9 TR-6060 from an LSA-powered CTS-V needs the MG9 adapter, not the standard TR-6060 one.

Notes from the BRP adapter product listings. No Vega install guide was available.

1971-1977 Vega LS transmission mount adapter FAQ

Which gearboxes do these adapters cover in a Vega LS swap?

The CTS-V T-56 and standard Camaro TR-6060, the MG9 high-torque TR-6060, the 2009-2014 CTS-V 6L90E, and the 8L90E and 10L90E. BRP has not published Vega-specific fitment for any of them.

Will a TR-6060 or 6L90E clear the Vega transmission tunnel?

No BRP source answers that for the Vega. There is no Vega install guide on the guides page, so measure your tunnel before you settle on a transmission.

Are the automatic adapters meant for a BRP crossmember?

Yes. The 6L90E and 8L90E adapter listings both say they are to be used with BRP transmission crossmembers. Neither listing names the Vega crossmember.
