True, my point was that the later parts interchange with the 60's. And you can run a pre-2009 70 in place of a 60/65. Also none of these trans is strong in stock form anyway. I have seen 4l70s break in stock trucks as well with stock tunes. Its all relative any aftermarket parts usually make it better.

Yup! 4l65/70 is way better than a 60, though

4l60's bust behind stock 4.3's

Did those with DBC do an IAC relearn and set the TPS?

But I agree with Wayne, it needs a VSS.

No I haven't done a relearn yet. I'll give that a shot. How do you do an IAC relearn on these? Everything I read seems like you just get it up to temp, shut it off and then fire it back up. And run the A/C while it idles if you have it (I don't). Is there something I'm missing?

I'm also running through everything to rule out vac leaks or something dumb like that.

I have not had a VSS since I swapped in this 6.0 a few years ago. I have one on the shelf to add and will do that now. I never got around to it because it worked fine until the stalling issue came about after wayne's tune.

Basally its a idle relearn you remove power to the PCM then start back up. Sure Wayne as the manual and can quote it. I don't have access to one right now over seas.

The stalling issue is a symptom for no VSS.

I just looked back at your 'stock' tune and the one I sent you. The one you sent me didn't have things like the VSS disabled and was still testing for it. Same with other things like the MAF, trans, etc. I'd bet you had dozens of DTC's showing up. I simply took a TechII, reflashed your PCM to factory settings of the van, made some changes that you already had done and some additional for power.

What is the pulse per driveline rev VSS you are adding? Right now your tune is setup for 40, which is stock. Let me know that and what MAF you want it tuned for when you send it back.

Yes I think my sensor is 40 but I will confirm when I send it back.

It's somewhat of a moot point now but I was also wondering if the speed density tune might have been less sensitive to the lack of a VSS. In any case, I agree the VSS should solve it.

Thanks for the help guys, this has been educational. Not to mention it runs a lot stronger and is noticeably faster with the tune.

At least there's a plus side

No, speed density shouldn't have anything to do with the VSS. Only thing I can figure is that by not disabling the VSS, and having it fail, the PCM adapted to a failed VSS. By disabling the VSS, the PCM no longer tests for it and apparently assumes it's there.

I'm not sure if 243 heads are different or not. But I can tell you do not buy these headers if you have the 317 heads. They fit great, but when I went to install the spark plugs, the forward most pipe is almost dead center of the plug. Pulled them to see if it was just my wrench. Header will not go back on, spark plugs hits it. Guess you get what you pay for.

Found these headers on eBay for $168, figured they may help someone else's swap. They look to fit good with the Novak YJ mounts.

ordered these up tonight for $229, look like the tubes are out of the way.

I know the topic of oil pans have been covered a lot. I finally got my engine in and realize the truck pan is not going to work for me. I am leaning towards the f-body pan with a baffle. I have been looking a lot at the Holley LS conversion oil pan as well. It seems to have the best ground clearance but I was wondering if anyone was running one. I am curious about the baffles in the pan and how it works on steep climbs.

Bo185 · Jun 9, 2012

Pretty sure the holley pan isn't baffled, just has a sump cover.

Now i have never owned one to actually look and see. But be interesting to see the inside of one.

But the picture above looks like it would be easy to add an actual sump to it.

sleepsontoilet · Jun 9, 2012

I have a mast performance from any7offroad on the forum. $460, and has baffling, plus they ship another added baffle you can weld in.

On the above mentioned headers, got them in and they spark plug gap is day and night from the other eBay set. However, still a *#^# glitch! On the drivers the front primary tucks into a high spot on the collector and couldn't be made more perfect. The passenger side tucks into a low one and hits the Novak engine mount. These are for a 2010-2011 camaro. Not sure if I should send them back or cut a small notch and bend the tube upwards a pinch. you can see the difference in this pic.

I got a Cadillac CTS pan on my 6.0

what's everyone doing for their speed sensors? im using an old chevy 205 transfer case with cable output. im thinking of using a http://www.dakotadigital.com/index....ge/ptype=product/product_id=109/category_id=311/home_id=59/mode=prod/prd109.htm

SEN-01-4160 but im worried about how to get the programming on the pcm to get it to work right.and which vss input do i use

Can't seem to get a yay or nay on if this works, so I went ahead and ordered it today to try it.

Bo185 · Jun 11, 2012

Whats the output signal? The range can be changed in the PCM.

SEN-01-4160 - 8K pass-through pulse generator with adaptor cable for GM transmissions with cable drive speed output.

This is what the webpage shows. No one would answer the guy whom asked last year, I've posted twice with no response. Can't seem to find another way to get a vss from a rfmvb 350/205 setup.

It really sucks that I ended up spending spent more to have my tranny rebuilt (just under $2,000) than I spent for the engine and tranny ($1700) at the start of this project. But for 2 grand they did all the removal/reinstall work, and I got full 5 gear planataries, a Beast sunshell, vette servos, a 9 disk 3rd gear clutch pack, yada, yada, basically a 4L70e, and with a warranty. But I am still 2 wheel drive as he couldn't find a GM Colorado tranny pan with the driveshaft relief built in. So I ordered one from my local Chevy dealer today, on backorder, so hopefully in 2 weeks I will install it and keep my fingers crossed that the skinny driveshaft will clear everything. THEN I can go to the dunes and have some fun. Of course, Jay says we don't need no stinkin front DS, just get a set of paddles. He may have something there. A little rough on the pavement though.

Now with just a little bit of throttle the rear tires chirp on every 1-2 shift, and with just a bit more, on the 2-3 shift also. Definitely a solid shift.

I ramp up the shift pressures when I tune, to keep the clutches from slipping and etc.. When he rebuilt it, I bet he put a shift kit in it, which also increased the pressures. So if I went 20%, he went 20%, that's 40% more.

Just let me know if you want to relax them a bit...

In the interest of full disclosure, I should note that I'm looking into a 2 piece shaft now...
But, it's not because the small one can't handle the torque of roasting 38" swampers, but because in certain flex situations the front driveshaft hits the lower link and gets bent. Once a shaft that small is dented or bent it doesn't have squat for torsional strength, and will wad up pretty quick. If I were running a somewhat different lower link configuration I still believe the 1.25" OD front shaft would be sufficient.
....but if my new 2-piece configuration allows a larger OD shaft I'll certainly take advantage of it!

What if you were to modify your trans pan yourself?

JayMcJay · Jun 14, 2012

My issue isn't as much the trans pan (which my various bent driveshafts have graciously modified for additional clearance....) as the front passenger lower link. I haven't figured out exactly what flex situation does it, but in a certain situation the driveshaft and link need to occupy the same space. When that happens the driveshaft is always the looser...

If I were to go to a larger driveshaft without adding a joint in it I'd just hit my lower link sooner.

Wayne, Will my tune work with this, or will I need to send the computer back, or something different entirely for a vss signal?
