8HP Aluminium Gearbox Sump Pan Kit - BMW, Jaguar & Maserati - 8HP45 / 8HP50 / 8HP70

ZF 8HP Aluminium Gearbox Sump Pan Kit

We supply this ZED Performance aluminium gearbox sump pan kit for selected ZF 8HP45, 8HP50 and 8HP70 automatic transmissions. You recieve the pan with one fitted filter and two spare filters plus a rubber sump gasket, 13 sump bolts and a gearbox electrical connector sleeve.

The aluminium pan uses a replaceable filter. At future services you can retain the pan if its still in serviceable condition and replace the filter and required seals. Transmission fluid is required seperately.

What comes with the kit

• 1 aluminium alloy gearbox sump pan
• 1 fitted transmission oil filter
• 2 additional spare filters
• 1 rubber sump gasket
• 13 sump mounting bolts
• 1 gearbox electrical connector sleeve for renewal where applicable

Vehicle and gearbox compatibility

This kit replaces the original plastic sump on selected applications using the sump family referenced below. An eight-speed automatic gearbox or a matching model name alone doesnt confirm fitment. Check the gearbox identification and original sump number as well as the filter pickup layout and clearance for the aluminium pan.

These are applications to check rather than guaranteed fitment for every engine or drivetrain. Jaguar manual and six-speed automatic versions arent covered. Maserati hybrid models need separate confirmation. This listing doesnt cover 6HP or 8HP90 gearboxes. Other 8HP variants also require a separate fitment check.

Original sump and service kit references

These references identify the original sump or service kit family for comparison. This aluminium conversion is an aftermarket product. Its not a genuine BMW, Jaguar, Maserati or ZF kit.

Keep the spare filters for future services

The original plastic sump combines the pan and filter in one assembly. This conversion uses a separate filter so a complete plastic sump and filter assembly isnt the replacement filter for the aluminium pan. Keep the supplied spares and your kit details together so the next service uses the correct filter.

Check the pickup layout as well as the bolt pattern

Compare the filter pickup position and connections with the original assembly. Also check pan depth and clearance around the undertray and crossmember. A pan that bolts to the gearbox can still have the wrong pickup arrangement.

In an owner discussion about ZF 8HP sump conversions drivers found that their original filters had a second pickup connection missing from the aluminium replacements they had bought. The discussion concerns a different vehicle but highlights why a shared 8HP gearbox family alone doesnt establish compatibility.

Have your VIN, gearbox code and original sump part number available when requesting a fitment check.

Fluid and filling procedure

Use the fluid specified for your exact gearbox and follow its filling procedure with the vehicle level. Read transmission oil temperature with a suitable diagnostic tool rather than judging it from the outside of the pan.

ZF service information 50130 gives a general oil level checking range of 30–50°C and a Maserati range of 50–60°C. Follow the procedure applicable to your vehicle including the engine running and gear selection steps. Dont assume a BMW filling guide applies unchanged to a Maserati.

Use the tightening sequence and torque instructions for this aluminium pan and its supplied fasteners. Dont select a torque simply because the original pan was plastic or because another replacement pan is aluminium.
