Tiptronic Transmission Swap In 986


Recommended Posts

Hi

This question is for Lauren.... or somebody that face the same situation....

The transmission in my Boxster 2.5 1997 reach the end of it's life a 160 000km.... start slipping and jumping between gears... So probably clutches and torque converter problem.

The transmission was check for oil condition and level, and it's was perfect... the oil was changed twice in the last 5000 km ....

So my Porsche technician propose to swap instead of rebuilding with an almost new transmission from a 2001 2.7 boxster, but I'm not sure if it's compatible with my control unit...

I got a ZF 5hp19 model A86-00 ( porsche 986 300 911 01 ) with control unit 986 618 225 00

and the part proposed by my Technician is a 5hp19 model A86-05 ( porsche 986 300 011 05 ) , and I think that it need a control unit 986 618 240 00

My question is: Will this transmission work with my control unit, or could it be reprogram for the new tranny ????

Thanks in advance

I know the 986.300.011.02 required a newer control module so I expect you need the newer control module for 02 and newer versions.

Perhaps RFM knows for sure?

Thanks Loren...

Do you mean 986.300.011.20, because I know that this one required a specific control for Boxster S.

But now, I think that I have no choice... Today, After a Big Clunk... the Tip turned into safety mode....

So I will put the used A86-05 986.300.011.05 and see if it's compatible.

Wish me good luck... and hope to be back on the road without any issues in 2 weeks...

@ El Acura, check PM.

Thanks Loren and RFM

I will provide these informations to my Technician.

I also will keep you informed about the issues of the tiptronic swap...

For sure I will change the RMS and IMS at the same time...

Best regards

Update

My IMS bearing was as new... but transmission not in yet... should be tomorrow...

not the same luck with the 1999 boxster S that was on the lift next to my car

The car was in for an oil leak... and end up with a LN Engenering bearing upgrade...

BTW my tech told me that it was pretty easy to remove the double row bearing with the puller fron LN...

2001 transmission work flawlessly with the old 1997 control module.

but the tranmission ratio seams a bit different then the old one... I've hit the 30 miles per galon with it...:thumbup:

Total cost $3000 with tranny, IMS, RMS, and Air injection valve... not too bad...

Special thanks to Loren and RFM

Loren... Is this spur gear located between the transmission and the final drive????

If the ratio is different, that's probably why I have almost 6 KMH difference at 3000 RPM...

Thanks for the Help
