2.5 TDI AUTO TRANS thread

[Greg Roles]

been a long time since my gearbox was done, but Dave at Automatics of Marion, did some of his own fixes to the box, and i seem to recall him mentioning placing some dowel pins in there to stop certain things from spinning unnecesarily, and wearing out

Yeah that sounds like the "spinning k2 clutch bush" problem I'm fearing. Sonnax have an upgrade bush, the drama is you have to pull it entirely apart to get to it...

All fingers, toes and other appendages are crossed all my issues are just the valve body. I would actually think so, as this 3-4 flare is something I created by putting the shift kit in the valve body, and / or the fluid flushes along the way stirring things up.

Hope so anyway....

Fluid flush / change is what killed ours after the idiots at VW dealership just did the bolt removal to drain and then refilled from the top again in another bolt , the new fluid flushed out all the gunk which then blocked the fluid filter/ pickup at the bottom of the sump which then killed the rest of the internals as it did nt allow the fluid to get through to the moving bits and pieces .

Gidday, I choose this tread to ask a question as it has a lot of great tech info by knowledgeable members.


Background:


I have a 2006 Kombi Beach (a multivan platform), it has a AXD 2.5 96KW non-DPF with an Aisin 09G JAD code 6 speed auto. Van has 239,000 and hit a roo 2 years ago, I’m currently getting it back together for a blueslip (NSW).
Auto seems ok but has only been driven around the block due to no rego. My focus has been on fixing engine and panels etc.


i might have an opportunity to pickup a low km (135,000) Aisin 09M JUL code 6 speed auto from a 2007 3.2 petrol engined van. I’m just looking at this as I’m building up an inventory of spare parts. The Beach is a keeper so hoping to keep it as long as it hangs together.


I noticed a UK wrecker was selling a JUL code auto which was salvaged from a 2.5 BPC engine so I was hoping the JUL was not a specific box for the 3.2 petrol engine.


Question:

Does anyone know if the JUL will simply bolt onto the AXD engine without mods to transaxle etc. Would there be any software / ECU considerations to think about.

Cheers Rob

wouldnt the petrol engine version have different ratios or final drive, versus diesel?
I'd be checking every spec on another box, for compatibility, before you commit.

sorry, can't answer your Q.

Thnx Steve, I’m trying to find some specs on the JUL box for comparison as you suggested, JUL doco is hard to find on the web though.
