4L60E questions Hey everyone im hoping to get an answer to a question i havent found online yet. I need to put a gear position indicator on my 4L60 and Dakota digital and lokar both make them but i can help but think that maybe this function is already in the box? It is a fully manualised trans so no computer involvment at the moment so im wondering if there is a way i can wire the plug to show what gear the box is in ? If anyone knows the electrical side of these boxes well i would love to ask some questions. Thanks all.

What model year is the Transmission... or is it a stand-alone transmission bought over a parts counter?
What vehicle is the Transmission from if it was not bought over the parts counter?
What type of vehicle do you have with this Transmission in it?
Are you asking about an electric/ electronic gear selector position indicator... or just a linkage/ manual type of indicator?
Which Dakota Digital and/ or Lokar products are you looking at?
If your Transmission is a 4L60E unit; the internal and external line diagrams and block diagrams (schematics) are very well known, and we can post them here for you.
Thanks for creating a new thread on the forum to ask your question/s.
In the future; please try to include as much pertinent information as possible along with your question/s...
As it would be much faster and easier for forum members to respond to your question; without having to ask you several questions back, as I just did.

Ok so its a 4L60E out of a 2003 VY SS Commodore. It and its attached LS1 have been place in a 2wd 93 spacecab toyota hilux. Dekota digital have a unit GSS-3000, The lokar unit CINS-17002 operates in the same way. Basically im wondering if adding an aftermarket unit like either of these is avoidable?

I am still confused as to what exactly you are trying to do. You say you need the "gear position indicator" but do you mean the shifter position (D1, D2, D3, OD) or the actual gear that the transmission is in?
The bigger question is "WHY"? Is it because all electrics have been removed? If true then how does it shift? If a fully "manualized" valve body we would need to know more about that.
As vorteciroc hinted, the stock 4L60E reports the shifter position through the harness to the PCM/TCM. It does NOT report the actual gear the trans is in; that would require a computer module comparing engine RPM and MPH and I'm not aware of any such unit. Correction: I now recall a relatively simple box which slices into the shift solenoid wires in the harness and displays which gear the PCM has commanded.
A somewhat similar thread which has perplexed us all is this: https://ls1tech.com/forums/automatic...eing-gear.html
Reading it might confuse you more, but vorteciroc and others have posted very useful and information about how the internals of the 4L60E report the D1,D2,D3,OD position and an external switch reports the additional Park, Reverse and Neutral positions.
Does this help you out?
