anyone know what trans mount I need to use for the 4l60 with the stock crossmember? the transfer case adapter appears to be narrower at the points where factory trans mount would bolt

Does this help paint the picture? I think you might have a reg 2wd mount instead of a AWD. The mount pictured is for the factory setup

How about a stock mount? 4L60 was the stock transmission. The square tube Crossmember was stock in all AWD T-Series.



I read this sentence 10 times. It's very poorly written. What are you trying to ask? If you mean the bolt pattern on the T-case adapter has a wider spacing than the bolt pattern on the rear of the transmission case, you are correct. The two patterns are different. So is the usage. The holes on the transmission case are used in 2-wheel drive applications. The trans mount for a 2-wheel drive application is much smaller, and has a single stud to the crossmember. In a 2-wheel drive, the trans mount doesn't carry nearly as much weight as the trans mount does in a 4-wheel drive, so it can be lighter-duty. And is.

There are also 3 different crossmembers. 2 wheel drive, 4 wheel drive, and All wheel drive. The AWD crossmember is shaped differently on the driver side for clearance at the front propshaft. It is also square in section, the other 2 are round in section. The 2-wheel drive crossmember positions the pad for the mount forward to correspond with the forward mount position. The 2-wheel drive crossmember has a single hole in the mount pad. The 4X4 and AWD crossmember have 2 bolt holes in the pad.

And there are 3 T-case adapters: 4-wheel drive floor shift (3 threaded holes for shifter), 4-wheel drive with electronic shift (no holes for shifter), and All wheel drive. (No holes, clocking position of T-case pattern different than the 4X4 adapters). The transmission mount pattern is the same for all 3 adapters.

There. Maybe your answer is in there somewhere. I have no idea what you're asking about.

sorry for my poorly written question. I'll work on my delivery and essay writing skills lol.
but yes I am asking about the mounting holes in the trans adapter where the trans mount is bolted too. it has a narrower bolt pattern. I am guessing from your statement that it is a two wheel drive version. my question is there a certain year mount that I can get that will bolt up to the 4l60e and have the two bolt pattern that goes into the cross member?

Re: 4l60 trans mount?

I have a 4l60e done up by rpm that I bought from a member on here and the bolt holes where you would mount the Trans mount too is to narrow for my stock 4r70 Trans mount to go on. My question is there a certain year Trans mount that I can get that will bolt on ton 4l60e and still have the two studs that go into the stock crossmember?

Re: 4l60 trans mount?

What Dave is trying to explain to you is that the trans mount attaches to the Transfer Case adapter, not the trans. So as long as you are using a SyTy transfer case adapter on the 4L60 you shouldn't have a problem. If you are not using a SyTy adapter, then you will have more problems than just the trans mount. If you are working with a 4L60E, not all cases will accept the SyTy transfer case adapter. I had to supply RPM with a specific one piece 4L60E case that was only available for two model years when they built my trans..

Re: 4l60 trans mount?

Dude it's simple. Yes it's a Syclone .The Trans adapter on my 4l60e that Iam installing will not except the original 700r4 Trans mount out of my Syclone. I was trying to just find a mount to put on and go from there. Obviously I have some sort of custom Trans adapter that is not normal and I'll will just find a Syclone 700r4 adapter and go go from there. Obviously because I have some sort of weird Trans adapter which I don't know what it is it has throwing you for a lope . Appreciate your help and sorry for the confusion.

Re: 4l60 trans mount?

Unless your 4L60E is an early 1 piece case with an F cast in it, the stock SyTy transfer case adapter will not bolt up. Early cases have 4 mounting holes for the extension housing or transfer case adapter and later cases have 6.

Re: 4l60 trans mount?

barrowed a syclone transfer case adapter from a buddy and all is good now. thanks for the technical help and history lesson on transmission differences.
