Anything I've missed?

Thanks in advance

All videos/advice and tips I've seen about these ZFs is that you fit the converter and then measure the distance from the converters mounting to the face of the engine-trans face and there is a specified distance for various models. I first saw this on Ashcrofts, and then various fora and then U-tubes. This is to ensure that pump has been set properly ... not just set and forgotten.

Thanks Arthur,

Do you mean fit the converter to the transmission or drive plate?

I assume what you describe is a different way of doing what is in the manual that I've outlined above.

Always fit the converter to the transmission. Always. PITA getting bolts in but if you do it the other way and fit it to the drive plate you will almost certainly destroy the pump when you offer up the transmission

You can feel when it engages properly. Apply firm pressure while rotating it. It will go in and seat but keep going because it will probably go in another “seat””
,if that makes sense. Take your time because you don’t get a second chance.

Correct. You can feel when the ears on the TC engage with the pump.

In my case (C9) it was easier with the auto standing on its tail end, the TC drops down noticeably when properly engaged. Take your time............. I thought mine was engaged, but it really wasn't at first.

The check is when you offer the trans with the TC installed up to the motor. using a couple of pilot studs.......... there should be a gap between the flex plate and the TC of about 2mm when the mating surfaces of trans and engine meet. This is your second and last chance to get it right.

If there isn't such a gap something is WRONG and you shouldn't proceed until you work out what it is.
