It actually does include the torque converter. my coworker with his S3 4.6is paid $3017 out the door with a 10% markup from the parts department.

I dont think I ever posted any pics - here it is after I got the first layer of filth off. Ready to mount the 87's but no sense in doing so until spring.

Here's the link to an album. Couldnt figure out how to post a pic in thread.

What software are you trying to load the files from?

x5Alp - That pricing sounds like cost thought. Unless Duke has a special hookup, isn't dealer more like $5+....

Nah, you can buy it wholesale from the dealer online. A BMW dealer in ATL was $2910 or so for the unit.

But, it is the same unit from 17 years ago, new or not. So Im going the other route. Valve Body from RevMax has new solenoids and other improvements, $600. Re-man TC is $215, also built beyond OE spec. Then the rebuild is $900 and another $500 labor to swap.

The supercharger is at Vortech as of today undergoing inspection! Hope its on the way back from the west coast soon. Feels like this is going to take until March.

Phil, I’ve found a transmission that was rebuilt 15k miles ago, but has 215k miles on it. Should that be a concern? The shop says they did the works on it. Torque Converter, full clutch kit etc & valve body. I’m just wondering if i should be worried of the overall miles, or should it be alright & i’m overthinking it?

Thanks for your insight.

The ‘incorrect ratio’ codes imply that the signals taken from the turbine and output speed sensors do not add up to one of the ratios (for 1st & 3rd gear in your case) i.e. a clutch is slipping

I see 5HP24s at that mileage quite frequently and they’re in excellent condition (but others are completely ‘worn out’ at much lower mileages). When I check the thickness of the friction plates at 200k miles they’re often identical to brand new plates because the control system is so sensitive to any unplanned clutch slip that it immediately flags failsafe if there’s anything going on that could generate wear and damage. The long-term adaptions stored in the controller tweak the clutch control pressures over the years to maintain the shift times, again, protecting the clutches. Arguably at such a high mileage you should swap the controller with the transmission to preserve these settings.

Clearly, it’s a bit of a lottery fitting something at that mileage without knowing its duty-cycle history. If it’s been driven gently for the whole of its life the transmission could last indefinitely. If it’s been used for towing, frequent hill climbing, driven aggressively, etc. it may be much further through its fatigue life. Similarly, you have no way of knowing if the fluid has overheated in the past and therefore oxidised and massively reduced its protection/life.

Common failures at high mileages are the A-clutch drum snap ring groove (for transmissions built before November 2000), the B-clutch hub/C-clutch drum axial bearing failure, the F-brake piston seal (for transmissions built before August 2001) and wear in the torque converter lock-up clutch. Other than these well-known weaknesses the rest of the transmission is very durable. If the transmission has previously been rebuilt then the above issues may already have been addressed? Transmissions built after October 2001 have all the latest development fixes from the factory. If you want to know the date of manufacture of a particular transmission just let me have the serial number off the green plate riveted to the side of the casing.

I spoke to my shop yesterday and they said Vortech hasn't even touched mine yet, and it's been there since last Monday. Hopefully they'll get to it today!

Damn...feels like its gone be awhile.
