Be careful of the compatibility of the Mem-cal to the 4L60E transmission.

The VR & VS V8 auto computers are the same, but the mem-cal is different depending on the trans you have.

The transmissions are identified by the serial number. This appears in 2 places. One is a sticker on the bell-housing, & the other is a stamping on the main case near the pan gasket.

The important number is the first digit. If your trans is a VR then this will be either a 4 or 5 (relating to the 1994 or 1995 model year).

The function of the 4 is different to the 5 (& the 6 ) & so on.

Post your serial number & I can help with the mem-cal.
