Hexagonal Screw - sump pan retaining screw for the ZF four-speed automatic transmission.

The screw passes through one of the pressed retaining plates and threads into the transmission casing, clamping the pan lip and its gasket against the casing sealing face. Because the clamping load is carried through the plates rather than a bolted pan flange, the screws must be run down evenly and torqued to the specified figure in the correct sequence - pulling one down hard before the others distorts the pan lip and produces a leak.

Supplied individually. The screws are commonly renewed as a full set during a fluid and filter service, particularly where heads or threads have corroded in place.

Frequently asked questions

What is the RTC5735 hexagonal screw used for?
The RTC5735 is a sump pan retaining screw for the ZF four-speed automatic transmission. It passes through a pressed retaining plate and threads into the transmission casing, clamping the sump pan lip and gasket against the sealing face.
How many RTC5735 screws are needed for the transmission sump?
Several RTC5735 screws are typically needed to secure the ZF automatic transmission sump, as the pan is held by a ring of screws through the retaining plates rather than a few bolts. Count the fixings on your pan, and it is good practice to renew them all when dropping the sump.
Which vehicles use the RTC5735 transmission sump screw?
The RTC5735 fits the ZF automatic transmission sump on Defender (1987-2006), Discovery 1 (1989-1998), Discovery 2 (1998-2004), Range Rover P38 (1994-2001) and Range Rover Classic (1986-1994). It suits the ZF four-speed auto, so confirm your vehicle has that gearbox.
