How to manually shift your 4l80E.

[@ronniecox109]

For a bad ass 4L80E , rebuild with the red frictions Raybestos HP2, use a Transgo 4L80E -2 Shift kit, the 4L80E-3 is the kit that adapts a modulator valve inside the pan. With this mod , no electrics, no switches. Full manual , up shifts , and down. Have several of these units in single , and twin turbo LS combos. The valve body and pump mods, make this unit virtually bullet proof. Units available. Hammertyme Performance Engines /Transmissions. Hampton ,Ga.

I used a trans go manual valve body kit

@@JUNKYARDGTO how has it worked for you? And what you got in front, engine wise?

[@davidgonzalez9785]

Great video and helped me out a lot. Thanks

just install the 48 MOD vaccuum modulator in your trans ,takes about 2 hours after draining,this controls the shift quality to normal levels,and will not blast the rubber pistons in half,full line pressure is a no no,i put all ignition and this kit in my motorhome,the engine wiring burned up to due a squirrel building a nest on the engine in storage,works great,in a motorhome it's perfect,no slipping,do not have to change gears on the hiway unless to fuel or make a turn,my motorhome has a point distributor in it,wanted to get away from all electronics except the dash ,worked thanks to chevy power

Thanks for the info. I was curious about that.

Do you have the links to where we can find the wire diagram please

I am looking at the 4L80E-3 kit with vacuum modulated pressure, but still trying to figure out how I am going to adapt the lockup switch. I did not see any instructions on the trans go site. Thanks for the video.

[@Dannymclovin]

So we can do this and add the vacuum modulator? Would this be a better combo as oppose to not running the modulator

[@Keeterbob]

So. I splice A and B wire from the manifold and the ground of solenoid A together. And C wire to the ground of Solenoid B. Switched power to the pink wire. External switch to brown wire. Then I just manually shift the mechanical linkage on the trans to get 1-4 gear?

[@austinbaker93]

when i hooked up switched blk wire on 4l80e to ground there's no lockup any ideas

[@oceanwaves83]

How about the shifter itself? Who makes one that works well with this setup? I'd definitely need one that is incapable of a money shift (stops you from downshifting without pressing a button). Is stuff like that out there?

[@johnsimmons8456]

Have you tried grounding the TCC wire and locking the converter by a manual switch? When you lock it in 4th, is it just firm or does it shake/vibrate the car?

[@davidvonanderseck8649]

Man so cool thanks

[@BlueFireR6]

Cool shit dude

[@drift199]

do you have any videos how it shifts?

[@camaroboi13]

If you only have two wires hooked to it, how is the shifter connected to the transmission?

[@Tota1Everything]

Ok on the transmission itself it has like a knob and you twist it to put it in gear. To shift it is automatically manual to begin with. But the computer is what controls the pressure for it to shift

[@tonyballone3004]

Is there any shift delay when using this method?

[@ChopsMahone]

Not really. About the same as a regular trans setup

[@zragevii4705]

How well does this drive, and did it grab all 4 gears

[@nitrousshovelhead]

please stabilize video

[@jamesminchew8404]

Wtf do you know how it's wired to the shift selonoids
