How did you adapt the Chevy Bolt pattern to your Big Block Mopar? Is your 4L60E the removable bellhousing type?
Do you have a thread about It? I've been looking at doing that swap, I beleive the Terminator will allow me to control GM trans. My hang up is I just installed a brand new pan and am hesitant about cutting it up...Ive never put a TF and 4L60 side by side to see what the actual differences are size wise....With the QuickTime housing, I had to convert my input shaft and torque converter to the 300mm, as well as use a hub spacer. If I had to do over, I would not have used the QuickTime housing. That being said, I’m happy with my result.
Yes I do. However, I'm not done yet. The car had to get put on the back burner for family and house projects. I'm running the microsquirt trans controller and a us shift throttle position sensor on my edelbrock. I think the trans controller is around $400 with the harness. It is one of the cheapest available. Here is a link of what I have. https://www.forbbodiesonly.com/moparforum/threads/4l60e-to-a-big-block.48547/ I'm actually going to try and get the wiring finished next week while on vacation.Do you have a thread about It?

2k for a OD BBM...sounds pretty reasonable... I have a friend that has. Gv unit that he took out to replace w/ a 6 dps has about 2500 miles and is asking $1750...I would still need to get a drive shaft, and the right tail housings which would put me over the $2k...
Thanks
Thanks, the LS style transmissions present an interface problem with the torque converter spacing and construction. The pre LS removeable bell trans with 298MM converter is what Silverstar uses and they have a dedicated cast bell of their own design. JW trans in Florida makes the UltraBell but not for this trans, same with Reid Racing. It can certainly be done with the QuickTime bell but there are some hurdles. The easier swap to a 700R4/4L60E is to use the earlier non removeable bell trans and an adapter such as the offerings from Wilcap, at least that has been my experience.
I was looking into this a while ago as I can actually get these transmissions here, as opposed to the 518's etc. But not being a chevy guy I struggled with working out what GM transmissions would work with the wilcap adaptor. they list it as 350 pattern suitable for v8's up to the LS - so is that any trans that will bolt to a chev V8 engine up until the LS? so it will suit the 6L80? 6 speed would make the effort worth while!
I did just that on mine. It was behind a 460. I was able to trade the adaptor case with GV plus a little dough for what I wanted which was the mid length unit used on RV/truck applications so I wouldn't have that unit hanging off 18" plus. GV was 30 minutes from where I used to live. While I was doing that, I decided might as well have the unit checked out before it got used in the car. It was toast and needed to get redone which they did as an exchange. By the time it was all said and done, I was $200 or so from just buying a new unit outright. Food for thought and luck of the draw for me.overdrive units hanging out in the rv wrecking yard. the bolt up to the 727 and most of them are still bolted to them. unknown what brand they are but in az cost have been from 250.00 up. just a thought you might be able to just pick up tail shaft and overdrive without having to buy the whole trans. again just a thought
The section where the overdrive is located is in the tailshaft. Because of that, the tail shaft is thicker and the overall length is longer. Classic Mopars were likely engineered to allow just a moderate amount of clearance to fit the transmissions that were being used at that time. The 518 series is larger so clearance is a problem. From what I have learned, the U shaped channel that serves as the torsion bar crossmember has to be cut out and a new one built with a higher "Arch" over the top of the transmission.Does it fit the stock tunnel? and what adaptor are you planning to use?
