So at this point, I'm tempted to put the factory van cluster back in. I found a CAN BUS scanner that claims to display the current gear, regardless of being in D or M. Everything else I wanted to see can be monitored via a BY OBDII scanner. Time to put it up on the lift for some transmission swapping...

I've considered the same, but looking closely at the Edge Insight CTS, I like that you can add sensors and you can use it for a back up camera display. I'd sure like to find a way to get to all the DIC data though..

probably just going to make one out of nylon round stock. Then extend the steering shaft as necessary.

Got some good work done on the van today. Driveshaft is out. Surprisingly, the exhaust unbolted as well, so saves me quite a bit of time vs cutting.


Got the starter out. Wow, that sucks. 30" extension bar is the best tool you can have. Trying figure whether it's better to install a new one when everything goes back together...

Started getting ready to pull the trans. All of the converter bolts are out. Cooler lines are disconnected. Everything is unplugged.

Trying to figure out what to do with this mess. I assume this protects the lift pump?


Small hiccup...I don't have the flexplate housing for the Allison. I'll have to get one coming tomorrow.

Quick question...my Allison came "bare". What should be on the side of the trans at the shifter selector? The 4L85E has this going on.


Sorry, long post.

Nothing; the 6sp Allison was redesigned with all of that inside it. You will need the 4th gen allison TCM and wiring harness from it to the transmission.

Sorry, long post.
That's the Fuel Cooler, cools the injector return fuel (it gets pretty hot being cranked up to 20,000psi). I plan to relocate mine to the front side of the fuel tank (where all the evap stuff is for the gas engines). But if you're staying 2wd it can probably stay were it is.

That is the 4L80e bracket.
The Allison bracket is more elaborate. The back of it is shown in this picture. http://www.ebay.com/itm/2001-2002-5-...5Y69Ep&vxp=mtr

Out with the old...


4L85E is out with minimal issues. Unbelievably good access around the bellhousing.


A rough eyeball says the dipstick tube is 8.25" from the face of the 4 speed. Same eyeball says the dipstick tube is 11.5" from the face of the Allison. I think I can make up most of the difference if I get rid of the EGR cooler. It's leaking, so I was planning for it anyway.

Anyone know how far the Allison dipstick extends into the pan? I could go off the manual, but I hear that Allison's are pretty sensitive to fill level...

Len, I ordered the shift cable bracket from a local GM dealer.

I agree, get rid of all the egr related stuff, cut the extension off the passenger up pipe and cap it (I'm going to install my egt probe there).

I'm planning to reach out to these guys:
https://www.powertraincontrolsolutio...ar_Indicator/#

Their page doesn't mention the Allison, but I'm optimistic...

Just for gear indication? Why not use a Edge CTS2 Monitor so that you can watch everything and plug in boost and egt probes?

I'll have to take a look at the Edge. I know virtually nothing about it.
