HarrisQ Posted March 14, 2007 Share Posted March 14, 2007 As long as the tranny is in good working order then I would say that it wouldn't hurt anything by putting in a shift kit. Quote Link to comment Share on other sites More sharing options...
Guest Posted March 14, 2007 Share Posted March 14, 2007 I've installed several through the years, and they are worth the time to do so. Even if it's strictly a grocery getter or a weekend strip warrior. Just don't get too carried away with thinking the STRIP version is the way to go VS just wanting to "firm up" the shifts.

MonteAZBB70 Posted March 14, 2007 Share Posted March 14, 2007 I'm no transmission expert, but my undestanding is a shift kit will actually increase the life of your tranny by reducing clutch slippage which in turn reduces tranny-killing heat.

Mike THAT IS EXACTLY RIGHT !!!!!!!!!!! I INSTALLED A B&M SHIFT IMPROVER KIT IN MINE LIKE 12 YEARS AGO AND I'M RUNNING THE ORIGINAL UN-TOUCHED 72 TH-350 !!!!

Mike 57 Posted March 15, 2007 Share Posted March 15, 2007 I agree with the above, the shift kit will not cure a transmission problem but if it is in good working order I think it extends the life of the tranny by not slipping the clutches between gears to make the shifts smooth. I have had good luck with both TCI and B&M transpak If you have never done one before the B&M seems to have clearer instructions for a novice.

Jared Richey Posted March 15, 2007 Share Posted March 15, 2007 Yes, like said it will inprove the life of a tranny. It helps the transmission change without slippange, the less slippage the less wear. But it also gives you a firmer shift, and at least in my car made it bark the rear tires when it changes, before the shiftkit, no barking tires when it changed.

The firmer shifts could potentially shock the rest of your drivetrain. Your diff, u-joints, etc. will take a little (albeit minimal) extra beating.

kc8oye Posted March 15, 2007 Share Posted March 15, 2007 I put a home made shift kit in mine ... a couple of tweaked springs while it was being assembled... a piece of broom handle in place of a spring...adjustable modulator.. and I can SPIN the rear tires going into 2nd @ 60 mph.

Guest Posted March 17, 2007 Share Posted March 17, 2007 think im gonna try the B&M improver for 30$ sound good. does it cherp 2nd and 3rd? thanks Paul Quote Link to comment Share on other sites More sharing options...
201fireman Posted March 18, 2007 Share Posted March 18, 2007 Ok, so there is a heavy duty and a street strip kit from B&M. Which one will make the biggest difference without being too much? Quote Link to comment Share on other sites More sharing options...
201fireman Posted March 18, 2007 Share Posted March 18, 2007 Also would you reccomend a stall converter and if so do you know one that would be good to use? Quote Link to comment Share on other sites More sharing options...
HarrisQ Posted March 18, 2007 Share Posted March 18, 2007 think im gonna try the B&M improver for 30$ sound good. does it cherp 2nd and 3rd? thanks Paul I put a B&M shift kit in another 72 Monte that I had. It had a 406 sb with a TH350 and it would easily chirp 2nd and if I was really on it, it would chirp 3rd. Quote Link to comment Share on other sites More sharing options...
HarrisQ Posted March 18, 2007 Share Posted March 18, 2007 Ok, so there is a heavy duty and a street strip kit from B&M. Which one will make the biggest difference without being too much? That would be personal preference. In my above post, I did the strip version but I wanted the tranny to nail 2nd and 3rd. As far as a converter, that would all depend on what your combo is. Get all your specs together and call any of the good companies such as Coan or ATI. They're a little pricey but good. I'm sure others could add to the list.
