Manual lever position sensor needed?
69 Camaro ls1 700r4. Swapping out the 700r4 with a 4l60e. My trans guy says the 4l60 e should have a manual lever position sensor on the left side by the shift rod. My harness was reworked by speartech and my instructions say nothing about wiring for the mlps. I was thinking I didn't need it but he says I do. Does anyone have any info how to wire this or if I need it at all. I have a call into speartech but with my work I'm can't always answer my phone. any helps is greatly appreciated.

Thank you sir! Was looking for a quick answer for my trans guy. I spoke to speartech and the camaro doesn't use a mlps it uses the trans Line pressure to inform the computer what gear it's in.

Trans Position switch
When I had Speartech modify my 06 GTO LS/4L65 harness for my 39 Chev 2d a few years ago they told me the PRNDL switch (attached to the gear selector shaft) was not necessary for trans operation and that they would remove it (although they forgot to). That switch tells the instrument panel what gear has selected, and provides info Park and Neutral start, plus backup lights. I have used a Dakota Digital GSS-2000 which can power individual LED gear indicators plus park/neutral and backup lights, about $100 when I bought it. The ECM gets trans info from the TCM through the big plug on pass side of the trans.

The MLPS (sometimes called neutral safety switch) doesn't have anything to do with the computer on any modelhin...it is used for things like the shift indicator on the dash...reverse light engagement...starter relay interrupt, etc
So...if you need something to send out a simpler signal (on/off) for neutral/park position...reverse position (for lights typically) etc...then you will want the mlps
But as for using it with an aftermarket trans controller...I have yet to see one that needs it...and if I see one, I'll assume they are hacks for using the mlps
