Thread: Torque converter.

Yes you can have your td5 torque converter modified to have a lower stall speed.

V8 torque converter is larger diameter which means strong lockup clutch

Are there any other, characteristics apart from the obvious fitment, between the two?
Can a Td5 converter be modified to emulate the V8 component?

2800 rpm stall speed on little td5 unit

2200 rpm stall on v8 unit

This translates to less slip at lower revs too, so as you take off you can feel the car move better in response to the foot as versus the td5 where it revs but the car plays catch up.

My POS is a very different (much improved) car all round since I installed the v8 converter (local bought used unmodified v8 converter and ashcroft fitment kit), regardless of whether I am running the td5 or v8 transmission controller (the trans control box under the seat).

I wouldn't bother modifying the td5 converter, basically very straightforward plug and play fitment of v8 converter with ashcroft kit and it goes fine with stock tune.
