4l60e better shifting

[Milesvtcalais]

Hi all, I was talking to a transmission specialist today and we were talking about shift kits for the 4l60e and he mentioned that you can adjust your force motor screw around 1/4 of a turn and it will raise line pressure and improve shifting. Well anyway I've got another transmission sitting around that I was planning to put into my car (not because mine is stuffed just because it's got lower km) so I know there are alot of people on this app who have some pretty decent advice and experience on transmissions so I thought I'd ask. What are some free modifications I can do to my transmission to improve shifting and overall enjoyment? I'm prepared to kill my transmission just to test this and I'll report back with answers to said modifications. When I say free modifications I mean that force motor screw and other similar things. I'm really planning on chirping 1st to 2nd eventually and I'd love to see this happen without breaking the bank
Thanks for reading all and please give me some advice

This is a cowboy mod and can cause problems if the amount turned is too much. A decent trans tech would be unlikely to recommend this mod. 1/4 turn could be enough to cause issues and once done it can not be reversed. I was offered this on my trans by a tech. I declined and I will no longer use him as that was enough for me to question the quality of work he does.

Can get cheap shift kits off ebay if you want to mess around come with various springs to hold gear as long as you want

The TCM commands line pressure by sending a PWM signal to the PCS solenoid, PCS regulates Torque Signal pressure which pushes Boost Valve which thru spring pushes Pressure Regulator valve which regulates Line pressure.
Messing around with these screw will unbalance the box so if the TCM thinks it was too harsh so it sets the shift learning to softer. You need more than a 1/8 to 1/4 turn to fix your desire feel, get a new shift kit for the spare and change it over and see if you like the feel if not then your better off having a Transmission place use a tech tool to adjust the settings.

Watched a video on bipassing the tcc pwm solenoid by filing a chanel into it so the fluid bipasses it not sure what this will do other then stop your transmission from slipping between gear changes proberly get bit of a jolt in changes after that

Hi there, I've looked into these shift kits and unfortunately the stage 1 kits include a overdrive or 4th gear lockout. I kinda like 4th gear not that I use it often but I drive my car to the track so its helpful for cruising

As mentioned I'm not worried about issues as the transmission has done its fair share of kilometers and I've got a new one to go in. It will be quite good to either see it work perfectly fine or go out with a bang

There are no simple free mods or everybody would be doing them. There is some stuff that can be done in the tune but any real changes need to be done mechanically.

Sorry it wasnt for between gear the tcc pwm solenoid i i forgot its just for when the tcc solenoid locks heres the vid anyway
