New Transgo 700-P 700R4 automatic transmission separator plate

This valve body separator plate fits all 1982-1993 700R4 Transmissions.

The stock separator plate in the 700R4 wears out very quickly.  Even after 20,000-30,000 miles you'll notice excessive wear from the check balls. Once these plates start to wear, you will slowly start to lose shift quality.  This can eventually lead to transmission failure.

This new Transgo separator plate is made from tougher metal and is also zinc plated, to make it a very durable item.

The improved universal advanced design allows one plate to fit all 1982-1993 models.

The 700-R4 and its variants were in production from 1982-1993 and can be identified by the square, 16 bolt oil pan and 4 forward gears.  1992-1993 are cross-over years.  If you are unsure of your model, the 700R4 will have a square wire plug with 2-4 wires, which are only for the lockup in the torque converter. 

The TH700-R4 was found in the full range of General Motors vehicles including, Buick, Cadillac, Chevrolet, GMC, Oldsmobile, Pontiac.

These transmissions can be found in the following vehicles; however you should double check your application with the 16 bolt pan count and square shape.  It is common for similar vehicles to have multiple transmission options available from the factory.
