cup plug is missing. Im guessing thats the issue. Fitted the BRF and had a lot better pressure differential (70 idle at 600 rpm - 150 full TV at 600 rpm). The brf does shift a tad on the high side at light throttle ( 2600 rpm 1-2) and 2-3 is a bit close as well. Might experiment putting the...

Interesting. The book certainly would help me! What I did notice on this VB is that the YV plunger sleeve came out quite easily. On my KC VB it is quite a tight fit. I can imagine it's leaking/bleeding pressure there. Imma pull the pan again on saturday and have a look, I'll inspect the BR...

https://youtu.be/IP0N5L5csTQ?feature=shared&t=960 Interestingly enough, in this video transgo mentions you need to remove the spring on the big weight whenyou have a performance VB like BRF or CZ.

See, I wonder about that too. I don't know how the transmission 'decides' it wants/needs to downshift. I dont know which valve it is + if it downshifts at an absolute pressure like 150 psi, or if it downshifts when it senses an X psi difference in pressure. One of the guru's will be able to...

Yeah, straight edge and feeler gauge. I think it was 3 thou but like I said, it was back in 2021 and I don't have anything on paper anymore :( Though I try to think about what could the issue be in the valvebody, as I had good kickdowns with the KC valvebody but not with the CZ I just swapped...

I have not. If it is better = bad pump? All parts are new (100 miles on it). To be fair, I thought pressures were OK because I compared them with the stock pressures. And thought something obvious in the valvebody was wrong, like the spacer in the TV plunger. Wonder if bad ATF could be the...

Update, had contact with Transgo, the boost valve is a .500" in their kit. With the fluctuations of the needle I think it might be the pressure regulator valve behind it? Or maybe it's just very very bad oil in there? Getting tempted to just throw a wad of cash at the car and buy one of those...

Hi, In the plate I added the aluminium slug and drilled the holes in the middle of the range they advertise. I have the transgo reverse/boost valves in there as well. I THINK transgo has a .472 valve as main boost valve? I did all the work in 2021, we had a fire after and I forgot quite a few...

Thank you! Do you know where I should be looking next? Pressure relief spring and boost valves? It has the transgo white PR spring with transgo boost valves (all in the transgo kit) You can see the needle fluctuating as well, maybe that tells something to someone. In P: connected -...

Edit

Hi all, I bought a CZ and BR valvebody because the KC vakvebody I had kept annoying me. I have the CZ in the car arm, as that should give me the best wot shift range according to the experts. But, it doesn't kick down like I want it to, it seems like it hangs in 3rd and won't go to 2nd when...

For anyone reading this in the future, problem is the wrong spring in the governor. I put the light spring from the stock governor on the small weight.

He can say what he wants... There's a very clear difference without measuring anything, GN has 18 working coils, "standard" governors have 14. That doesn't get into diameters etc.

Those are NOT the correct springs on ebay!!

Hi all, Would anyone have the specs of the small spring on the GN governor? I wanted to buy one at TCI but they discontinued it. Thanks in advance

Hi, As in the title, looking for the small spring on the GN 200r4 governor. TCI and all TCI resellers are out of stock. Will need shipping. Thanks in advance

That puts my mind at ease! I'm from the country of beer, chocolate and terrorists: Belgium :)

Update, Chris from extremeautomatics mailen me it's possible for them to source a core for me as well. That's a start :) I do hope the "no engine brake in 2nd" and stacked 2-3 shift will be resolved as well. But I'm hopefull. :)

I've sent him an e-mail if he could source a VB for me and add a core charge, might be a bit cheaper than sending my own VB across the world and back. Do you think it's possible to achieve 6k shifts with these?

See, I wonder why people have this issue and other shift consistently at +-6k. Maybe someone else will be able to help. On this side of the water finding parts isn't very easy either.
