Great video, very thorough and detailed, nicely done.

It might have already been mentioned but always replace or at least check map sensor and TPS. They can report back the wrong load calculations.

Great video!! Very well explained

What would cause my 2001 4x4 Suburban to shift super hard after descending off of a big hill? It will slam through gears until I shut it down and let it cool off a while.

I was thinking of upgrading my 1-2 accumulator but it looks easy to do the 3-4 as well. Can I do both without removing the valve body? If I'm on my back on the ground, how would I hold the check ball up? Assembly gel? vaseline?

I have the same accumulator housing you showed in this video on my 01 transmission I have a purple outer sonnax spring a couple inners and a couple other stock outers and a enhanced performance 77704s spring not sure which inner and outer to use? Any advice?

this would be a fine video but the instructions you gave for the 3-4 accumuator is upside down compared on the sonnax instructions

So I can use the older housing on my 01 then? I don't have the waved spring or the spacer so I wanna use pre 01 style housing if I can? Need to know asap thank you.

My question might sound dumb but do i need to replace all accumulators in the unit to pinless or can i just replace the 1-2 accumulator since others are working fine.

My wife agrees, we always make sure that o-ring is lubed up......😏. Now seriously, I'm rebuilding a 97 Tahoe for my wife and part of that build is making the transmission is better performing for the mild engine mods I did. Her Tahoe will be around 320-350hp and 400tq. Is a basic Sonnax upgrade kit good enough? Should I add their Corvette servos as well?

Hello ... Can you tell in more detail here in the comments, what is the iron plate for, and what does the new valve and spring do from this Sonnax set?

The separator plate is to change direction of fluid flow. And the valve with spring and plug change the apply for lockup and regulate the apply pressure.

Where can I buy that sanding stone you use on the case to valve body plate surface? I am not sure how coarse or fine it should be for just assuring flatness of aluminum valve body and mating surface.

Later must mean newer then 01 cause right under it it say 94 to 2000 doesn't need that spacer. You said your trans is an 03 so that would mean that it does need the spacer given what the instructions are saying. So please explain why the no spacer all over the screen.

As if it’s almost not in drive until I reach around 1300 RPM and then it kicks in. Same for reverse. Then in OD, the RPM fluctuates 200-300 every few seconds unless I’m above 60.
