I'm looking for a transmission dipstick for my 2020 Ultra Limited. 

I would be having a good look (with a magnifying glass ) at the female thread in the case.

Helicoil kit may do the trick ? Macgyver fix thread tape.

Thanks fellas, I have had a look at the case and it seems OK. It's more the dipstick and yes I have done the McGyver trick. I will have a yarn to an engineering shop tomorrow and see if they can recommend a Loctite product that might help. If there is nothing much else that I can do, I have this amazing idea involving a small piece of say 30 x 6 mm pine (maybe some nice Australian Cedar) worked over with a chisel and held in place with a zip tie . That'll hold the bastard in until I can get a new one ! I don't think there is any air pressure to push it up on that side because the primary side sucks.

Is that the actual dipstick ?

No , the actual stick looks the same but has stripped threads.

Well screw that one in then and Bob's yer uncle !

All fixed...... for now.

Good fix mate. One of a kind too.

Coming in very late and after the horse has bolted but I'll chuck it in here anyway, when putting that kind of dipstick back in keep the dipstick as close to 90° to the hole as possible and turn the bugga slowly backwards until you feel it drop into the threads, then turn slowly to tighten, if it feels wrong stop and turn it backwards again until it drops twice, can be 90° out, they suck.

Good advice GM.  Old retired carpenters can be a bit gorrilla fisted. Theyre good with chainsaws and shit but when it comes to the technical stuff they struggle .  

Someone's sure to take offence at this, talking about trans dipstcks...

Maybe not, providing you are not sticking your dipstick into trans.

Agghhhhh....... do I throw up now or in a minute !
