like the title said i just had this idea. mainly got wile look at a thread on another site abotu installing a B&M ratchet shifter and how it basicly is useless in a 4t65e

well then i got the idea that some have a switch on the side and that could be used for perfomance shift then i got this idea

Perfomance Shift has it's own shifting tables, line pressure tables, and shift time tables. basicly it just allows two diffrent transmission tunes in one. factory aplilcation was granny shifting/ more sporty shifting

my idea is that have it when it's in perf mode whent he range switch is in saw D it only aloows 4th it auto shifts dirrectly to 4th and will not drop out of 4th. we do this allready when dynoing holding the trans in 3 but with this we coudl have

1 posion be 1st gear only, 2 posion be 2 gear only, 3 positon be 3rd gear only, D be 4th gear only increase the line pressure and make the shift time be as fast as it can be safely then pusht he perf button to make it act liek a normal trans

could even have it be a revears vavle body D postion is 1st gear, 3 postions on 2nd gear, 2 postion is 3rd gear, and 1 postion is 4th gear


would it actualy help any thing? maybe drag racers like using manual valve bodies to help hold the trans in gear and pervent it from shfiting my trucks 700r4 had one

thoughts? would this be possible? i find it sort of liek tap shift after thinking about it

Well if i remember how a manual valve body works is you have to shift it manually every shift. Not just a when you want to. Also in order to have reverse shifting pattern it would be always be backwards and would be difficult to deal with day by day. A modified linkage I think would simpler and easier than modifying the actual valve body.

I think a good shift kit with a "performance " shift pattern with bumped pressures and custom trans tune on a switch / button would be the best way to go.

But I know a couple ppl that know them pretty well so if there is true interest I could look into it further.

my idea is to tuent he PCM to have whent he gear selctor is in 3 only have 3rd gear. when it is in 2 only have second gear

something like that it will be all electronicly controled no actual valve body modifications and witht eh perfomance shift switch you could put it back into a normaly funtioning automatic


wish i still had a tuner and a .bin file to look at.


hell all you really need to do is just have to switches to control the solinoids

That sounds much more reasonable., but not sure that a person can out shift the pcm. Hence program the pcm to shift at desired rpm and you will have a quick ( if programmed so) firm and most important consistent shifts. I have talked with Steve, Turbo Tim and a couple others that are into racing a bit more and every one says just put it in d (3rd) and forget about it.

I could see some benefit in an auto x setting by down or up shifting and having it actually stay there. But unless it was an auto x car that someone wanted street manors out of I still fail to see the "NEED" for it, other than bragging rights. Or some very few winter situations that a true second gear start could benefit.

i actualy have no idea what actual use it would ahve just something i thought would be cool to do witht eh useless perfomance shift button the 99 has seeing as it has a ZZP 01 PCM lol

going straight to 3rd would be awesome in winter. i did that with my '74 K10 with a manual valve body 700r4 that thing would not get stuck ever becuase of that

Well being that it is a simple on / off switch it could be used for just about anything. Most guys do things like bbv control, amp "remote " wire, auxiliary lights. Ect, the possibilities are about endless. I have considered using one for .... amp, strobe lights, led lights, bbv, auxiliary lights, brake light kill, even thought about using that button to do like zero did with the push button start. Ultimate anti theft. Only those that know could start the car then. Or just use it so that it pushed in the ignition works normal, if out then no start??

Imagination could do fun things with a button that looks factory and does anything else.


How about a sign in the back window that says " back off " or." tailgaters will be brake checked " and use that to turn on / off.

that is true

still think i might give the manual gear control idea a whirl though just becuase why not even if it fails worse case is i compleatly kcuf up the 99 lol

the trans even though it only has 20k on it there is something worng it shutters vilantly when it shifts into second at full throttle

i think they did not replace the steels when it was rebuilt and they are slipping

other than that i blame your luck.. it dont seem to matte what car it is you have goofy crap happen to every one of them.. either that or just poor choice in cars?? if you could afford it i would say get something with a warrenty, that way it would never break

proably i am pretty sure they just reused the steels that where burnt
