Getting a little fancy... 1987 V10

Ok so the torque converters are completely different. The 65e has a 300 milimeter converter and the 700 has a 298 milimeter converter. Along with having different input and turbine shafts.

The amount of upgrading you would have to do to the 700 to make it withstand the LQ4 is alot. You would basically have to put all the good stuff from the 65e into the 700, which is pointless. The 65e is a wayyyyy better transmission than the 700 anyway, PLUS your already using the computer to control the engine, as it also controls the 65e.

As Capt said, the 80e has a spacer between the crank shaft and the flexplate, the 65e does not use this spacer.

If you use the 700 behind the LQ4, your going to eat the 700 up pretty quick. It's much better to use the 65e that came behind it in the first place.

Now I know you got that welder to make a bracket for the 700 tv cable but if you use the 65e, then you can use the welder to make or modify and custom fit crossmember to support the transmission.

I have a built up 89 700 behind my 355. It cost me about 2 grand to get it high performance parts and get it built. The next time I upgrade transmissions, I'm gonna use a 80 series 4L or an allison from a diesel.

This is the best I can get while its on the stand. Sure looks like a spacer!

From that mess earlier to this..

To this.. Almost done then it will be mock up. At this rate I may mount the PCM under the seat!got plenty of length.

I showed the pics to our trans guy, he said it's hard to tell from those pics, you'll have to take it apart to find out. But being that it's a 65e, there is most likely no spacer. It doesn't really look like there is one there.

Have you decided to use the 65e or not? It would be the smart thing to do I think in this situation.

 Both left and right bank Fuel Injector wiring with the banks switched.
Can I bridge All the pink hot wires on each bank in an effort to clean it up. I plan to only have one wire from each bank using 12-10ga and solder each together and heat during for protection? Any thoughts? Mostly want to know if it will cause any interference with the injectors?

Yes I decided that I'd use a better tranny years ago. Firmly set on a 4l80...problem, my wallet barely allowed me to get an engine. So for now I'm gonna burn what I got and when the 700-r4 quits i will hopefully be in better graces with Uncle Sam and can afford my new to me tranny. Please oh please!!!

That appears to be a bell shaped flywheel indicating it was in front of a 4L60E.  to go in front of a 700R4, you need the spacer in front of that for the torque converter if that is the case.
For the Injectors the pink wires can be bundled together.

I' sure I wil need the spacer so thanks for that. The Vin says 4L65E so you are right. From what I have researched the 4L65 is just  beefier version with 5-pinion planetary and better 3-4 clutches. But the Torque convertor will bolt up without gouging out any holes? tats my real concern. I'm surely not comfortable doin that.

[Displaced_Txn]

the 4l65e is just a beefier upgraded version of the 4l60e, same bolt pattern etc. I'm using a 4l70e which is just another upgraded version of the 4l60e and 4l65e.

I cut the leads and spliced all the all time hots of the injectors to a single 12ga wire. I'm also going to turn the injectors in toward the fuel rails to hid as much of the wires as I can. Left bank is complete except trimming down the plastic guides to each injector. Slowly but surely its coming along. Gotta pick up some more 12ga tomorrow and settle on some loom. I really do not want to use the corogated OE style. I like the mesh type loom.

Looks like you are making good progress. Personally I would just wait and get the better transmission and not use the 700 at all. If your going to have to make the necessary mods to make the 700 work and then later on re-mod stuff to make the 80 work, you might as well just do all the modding ONCE. The engine came with a 65e, they are good transmissions, use it, it's cheaper than an 80. Again this is all personal opinion, I would use the 65e and put an 80 behind something with more punch than an 03 6.0. Something like an 8.1L with a supercharger or some high horse crate engine.

I'm a bit stumped tho as to what your doing with with injector wiring? Swapping pig tails and stuff? Can you explain further?

All I'm doing is giving myself the maximum amount of wire length to mount the PCM in the Cab. The PCM used to mount on the driver side fender. I intend on running it through the factory hole in the fire wall that the TBI ECM runs through. The right bank wires are a lot longer and by simply swapping them to the left I can gain several feet of wiggle room. As far as the soldering is concerned I'm simply cleaning it up a bit. Instead of having 4-16ga pink wires running from each bank I will only have 1-12ga plus PCM control wire from each bank.  Hopefully this let's you into my head a little. But be warned its a weird and often Scarry place...but I like it,they know me there!

Lol mines the same way, lots of cob webs but the spiders always smile and wave.

I get it now, for a second it sounded like the injector firing order was gonna be all backwards and then the motor wouldn't run lol I got it now tho.

 So I don't have any scrap laying around but I have this tranny jig that needed some reenforcement. Now it was first arc welded with a little CH welder someone gave me. That welder has a lot of settings Hi-Low-Off. Oh and out buddy jack was kick in out butts that night. Either way it will hold a 4L60E on a regular engine stand and makes life so much easier.


I am not an experienced welder. I have only used a MIG a few times for some exhaust and plug welds to put quarter panel back on the bed of my old dodge. But these were the first burns. Looks like I need to slow the wire speed a bit but heat for the 1/8th plate seemed good. A lot of the second weld looks pitted because I burned through the old weld. Any experienced help would be appreciated. I'm gonna be practicing a lot. And aluminum will be the next test.

every welder is different and according to this chart wire speed is your problem. if i was welding it i would turn the heat up a little and have a smoother pattern but that me and what works for me might not work for you.
