I've always refrained from trani work besides changing the pan and filter. But watching this video I know I can do it no problem. My spare trani is out of my truck so it should be even easier.
It is a pretty straightforward upgrade but can appear very daunting at first. Best bit of advice that I have is read & re-read the steps prior to drilling (or not drilling), be patient and do not hesitate to call our Support Team at 707-544-4761 with any questions, big or small! Good luck. - Jason @ B&M
Always soak the new valve body gaskets with transmission fluid before you install them. Also don’t torque the support plate bolts until after you have installed the main valve body and all of its bolts. The reason for this is because the separator plate can be misaligned and you will not be able to get all of the valve body bolts screwed in correctly if you torque the support plate down first.
I have installed these shift kits in numerous vehicles. They work great and improve the firmness of the shift. Quite often get a third gear tire chirp on the quarter mile.
If you run into any issues or have questions after install give us a call at 707-544-4761 where our Support Team is ready to help. - Jason @ B&M Racing
Some of these comments are just dumb. This video is to show how to install the shift kit. Common sense should tell you to reinstall the filter and new fluid. And most of the deep extra fluid capacity pans come with filter extensions and the longer bolts.
JUST A TIP...Always drill a valve body plate on a flat piece of old wood stock ad not on the edge of a table, warping those plates is never good! Great video though, I sure would like to see you do a GM TH350C video , it has much more work needed to do this conversion. Especially the, making sure the right size check balls are used in the valve body, I.E. 1/4" vs. 5/16th depending on whether the valve body is "as cast" or machined. Also using the original valve body plate as a template to drill 3 additional holes in the supplied plate. It also needs to be determined whether the factory accumulator body spring is stiffer than the included B & M spring, if it is... you do not use the B & M spring...These TH350c kits are widely used in 1981 and 1982 corvettes. Of which many of these cars are still on the road and are becoming wildly more popular...Stingrays are in! Thanks
I’m new to this mechanic stuff. 72 GMC truck. It likes to slip out of gear and lots of play. Mine is standard, so 1 will this work? And 2 is that what this is for?
did you remove the accumulator spring or leave it in? the o ring gasket that comes with the kit. That’s what u use when putting the accumulator cover back on after removing the spring.
@tapa2466 I bought it on ebay for 15 bucks don't know what came with it I had that n the cheapest b&m shift kit installed by a shop hardly a big difference but my friend had the servo alone installed in his camaro black n white difference compared to my shift kit n servo
@@joshup1275 ohh okay. in the video , he never showed it. But the removal of the spring helps the clutches engage faster and prolongs life because there’s less slip. and that gets good bite when shifting.
I watched another brand shift kit video, where they changed springs and other parts. What is the difference between this type of shift kit and others that require spring changes?
Sorry, I am unfamiliar with the installation procedures for non B&M shift kits and can't comment. This B&M racing Shift Improver Kit does not include replacement springs by design. This Shift Improver Kit is our entry level Shift Kit. The B&M Racing Transpak (part #30228) for the TH350 transmission is a step above this shift improver kit and includes upgraded replacement springs.

got the kit. used a video from th-cam.com/video/r1aEon7AB_g/w-d-xo.html&ytbChannel=null . he details two springs to remove to get a harsher shift. if this is done along with your kit.what is the result. further if bolth stage 1 and stage 2 are applied what is the result.
sorry not clear in my post. i rebuilt this tyranny using the above video. part 1 and 2. where the two springs were removed. one ball installed. i am now looking to put in your kit. as the tyranny is modified to one ball and springs removed. is their any point. the heavy duty kit has a extra oil passageway. to do what?
Our recommendation is to install this Shift Improver Kit on a stock, unmodified transmission. If your transmission has been previously modified I would suggest holding off on installing this kit. Of note, the installation instructions state to use 1 of the 4 check balls when modifying for "street & strip" and 2 check balls if modifying for "heavy duty". However, the instructions also state to remove and discard the accumulator spring (1) if modifying for "heavy duty" only. The accumulator spring is retained in the "street & strip" version. If your transmission is set up as 1 check ball and 0 accumulator spring/s you are running a mix of both options. - Jason @ B&M Racing
Nice video. I would really have liked to have seen a before and after short video of it shifting at part and full throttle

My favorite transmission to work on . I love the PG and 400 too .

That “taking care of business” tattoo thooo 😝👌🏻
Wow, I haven't installed a shift kit since 1992. 🤜🏿🤛🏿😎
SSR's comment was funny, but a seriously good video. Thanks.
This is defiantly going into my hot rod
THANK YOU SO MUCH I LEARNED SO MUCH.
Thanks for making this video. Picked up this kit for my stock th350. Seems pretty easy, can't wait for firmer shifts!

One of those new filterless transmissions 😂😂😂
Great video!!!! I understood this so clearly!!!!
Some of these comments are just dumb. This video is to show how to install the shift kit. Common sense should tell you to reinstall the filter and new fluid. And most of the deep extra fluid capacity pans come with filter extensions and the longer bolts.
What about the trans filter and doesn't it need a extension to work properly with the new deep pan?

Hi, hey on the 350 th pump what gasket sealer if any do you use on the o ring and the round gasket just behind the o ring gasket? Thanks in advance
A befor and after would be good
im sure he put that filter back in...... i hope
God made man with elbows to keep transmission oil out of your arm pits.
5:27 Do you put the the four check balls back in? You didn’t include them in the installation part of this video. Do you leave them out? Thank u
Only use one check ball for stage two.
I’m new to this mechanic stuff. 72 GMC truck. It likes to slip out of gear and lots of play. Mine is standard, so 1 will this work? And 2 is that what this is for?
Put this on my 91 305 tbi camaro stock n it felt a bit better but not enough of a difference as I thought

@@joshup1275 ohh okay. in the video , he never showed it. But the removal of the spring helps the clutches engage faster and prolongs life because there’s less slip. and that gets good bite when shifting.
but before you hit the highway fill it back up with trans fluid
b&m shift improver kit I need use also the 2 gasket and metal in middle?
I guess I don't get it. Add a spacer? No springs?

@@BMRacingPerformance perfect, thank you so much for getting back to me! I will look at the other kit.
Anytime! That's why we're here.
- Jason @ B&M Racing
@@BMRacingPerformance does the deep pan take the same filter as a stock pan?
Thanks guys
why no work to valvebody...bigger springs
You couldn't edit removing the pan?
Don't forget to add new oil to trans after installing the kit.
the servo valve fell out whenninpulled the valve body down. what now
How exactly does this help with towing?
Firm shift, less slippage when changing gears, especially when going up a hill. This can extend the life of the clutch packs etc.
One check ball
If your going street and strip looks like you used the wrong location at least looks like it on the video.
No filter
Don't need it I make my own
Why didn't Chevy include a fucking drain plug

Don't buy shift kit Google it show you everything you need to know about modifying your turbo 350
