Trans Question

Trans Question - 03/19/11 07:14 PM

Hey guys, I have a question if you could answer it. I just went to a 727 race transmission with a ton of aftermarket parts in it I drove it around the block and shifts fine. The problem I have is It seems a little soft shifting into 2nd gear. No slip at all and I have adjusted the front band. The transmission shifts real hard into 3rd gear but it just feels a little soft into 2nd. This is a old Turbo Action Manual valve body. I have not really shifted it under full power yet. It does have a pretty high 8" stall in it about 5500. Any ideas ?

Make sure the shifter is adjusted correctly before driving the car agian, the linkage end should drop into the shifter arm easily in all three forward gears, adjust as needed to make sure it does that

As far as soft shifting in 1st to 2nd gear what RPM did you shift it at? Maybe the converter is masking the shift some

Take that rascal out(somewhere safely) and shift it at WOT above the stall RPM of the converter(after checking the shifter adjustment) and see how it does there

Let us know your results

BTW when they shift real hard into high gear that is usually a sign of not disengaging the 2nd gear all the way before engaging 3rd gear

Some of the cars will seem harsh on that shift if your off of the throtle when shifting into high gear, depending on what RPM you make that shift at

Thanks Cab , The shifter is adjusted right , it's right on the money with the detent on the shifter. The trans shifts pretty hard into 3rd gear no matter what rpm I am at. I am hoping it's not hanging up on 2nd gear like you said. I will take it back out and hit it and see what it does from there. I will let you know . Thanks,

If the transmission is "right", with that valve body, you will feel the trans shift before you feel the shifter "click".

When on jackstands, you most likly WON'T feel it change into high gear.

If you arent shifting it with a good load on it with that loose a converter in it you just may notice it feeling different. Its probably in second just not engaging as hard as you would suspect because the converter is soaking up the "hit" of it...... that doesnt seem to make as much sense in writing as it does in my brain.

Thanks guy's . I took Cabs advice and hit it pretty hard. It hit 2nd real hard when I was turning it up. So far it seems to work pretty good.

Hey Kindafast.... If you have any other questions on 727's call Kurt at Magnum Machine (in your sig).... he has a lot of hardcore flite stuff for 7 and 8 second trans and is a wealth of knowledge.
