If you want it to shift like stock you leave the VB stock.. If you want to modify/improve the shifts you add a shift kit.




It does not shift like stock to me and it does not shift as a shift kit should as described on this thread. I was told by previous owner it had a shift kit but I guess I need to pull the pan and see what is in there. Again it shifts so smooth and fast that I cannot tell it is shifting unless I go real slow and concentrate. I have adjusted the kickdown linkage and replaced the missing spring but I will have to get with someone to look at this. This is such a headache it almost makes me want to install a manual 4 speed.




I don't really understand the problem , do you think there is a problem because you are not feeling your fillings being rattled loose by the shift? A bone jarring shift does not equal a good shift. Do you have a tach ? That will show you the shift is happening by the RPM drop.

Some shift kits change servo springs also so you just can't change the valvebody and think you are reverted back to STOCK.

What missing spring did you replace ?

also you say it has a high stall converter ? That means the engine may have a larger than stock cam that requires the use of a higher stall , if you change it back to a stock converter that will probably make the driving experience worse.




When I got the car the kickdown return spring was missing and that is the spring I replaced. It is not that I want jarring shifts but I cannot feel the shift at all. I have owned a couple of stock mopar auto 's before and I could feel when it shifted. The cam is close to stock. It is a Comp # CRS 268-H -10.




Do you have any idea how and how many miles the car was driven with that missing spring, that could be why the shift feels soft? What was holding the linkage forward before then?

Do you have an idea what the stall is of the current converter ?

Taking the shift kit out isn't going to fix the trans , also putting a shift kit into a trans that may have been close to needing a rebuild is going to make things worse not better as some might think.

Since you need to pull the trans to replace the converter I would get the converter you want , pull the trans and have it checked out , at minimum a seal kit is not super expensive.





I found the missing spring about 1 week after I got the car and was wondering when I braked why it would downshift so hard. I replaced the spring and adjusted the kickdown rod next to the carb as far forward as I could. I do not know how many miles the car had been driven as I bought it from a chevy dealer. I talked to the guy that traded it in and he said he only drove it car shows and I believe it because the car looked like it had just been restored but It was done 6 yrs ago. He had someone do all the work for him and he only knew that it has a high stall converter and shift kit. I talked to a mopar trans specialist that builds a lot of race transmissions and he thinks that by what I told him that the kickdown is out of adjustment. I am going to try to learn how to do it and if I have no luck I will have to find someone who knows these transmissions. I have never done transmission work before and thought I might try to pull it out if I have some indication it needs to be rebuilt or even to change the converter.

I adjusted the kick down linkage and man oh man what a difference! I can tell now what a shift kit is all about and it is a blast to drive! Floor it and it will chirp in 2nd gear. I could not contain myself and was running down the road like a teenager. Thanks for everyones' help and to those who mentioned that I should check kickdown adjustment you were spot on.

Good to hear!

Make sure that you can still achieve wide open throttle...... I have seen way too many adjusted to far rearward that the rod will impede the carb from WOT.

I usually start with holding the carb at WOT (after making sure the throttle cable is adjusted properly so it can achieve WOT) then adjust the rod to push all the way rearward on the trans lever. Hopefully that makes sense.

Thanks Don I will try that. I am learning as I go. Mike

You don't need to adjust the rod "to push all the way rearward".

With the help of guys on this site I finally got my trans kickdown linkage(or as I was informed, TPV linkage in MOPAR lingo) adjusted properly.

Some have the adjustments made by the carb, and some have the adjustments made down by the lever on the trans like mine. I made sure that the carb could move freely to WOT and that there was no binding in the linkage. Then I made some slight adjustments to the bends in the rod to keep it from hitting the engine block or binding at the trans lever. And then I made sure that the lever on the trans was pushed all the way to the rear when the trans was at wide open throttle. Finally I made very small adjustments foward/backwards in order to get the shifts where I wanted them while driving at part throttle. Once done, I double checked all the previous things about linkage moving freely, no binding, and proper adjustment of the accelerator cable. Night and day difference from the cobbled mess that I had before.

Lots-o-tweaking to get them to shift just right. If the engine is stock then the stock adjustment works fine, but with different engine modifications it takes a bit to make them shift at the right time.

Sorry John, you are correct that it doesn't have to be all the way back, I should have clarified that that is a starting point and can then be backed off from there.

I usually adjust for WOT shifting RPM then modify (cut and welding lever length....)the TV lever on the trans to fine tune to get light throttle shifting where it belongs.

I know its kind of a dead thread now but

Where to find a rebuilt or STOCK new valvebody for a 1971 727 Auto Dodge Charger ???

My valvebody has a lot of scoring/scratches on the shift valves and the selector shaft from the hard seal is pretty wore in spots also

Thanx Scott
