Since Im finally going to put in this TH350 as a temporary solution, it may need to last a while. My 87 SS is not a daily driver, but I would like to cruise in it when I can. I have a Coleman Taylor TH350. (got it cheap) Its several years old, but it has zero miles on it. It has had fluid in it, but its been covered up and all that. I plan to replace the front and rear seals. I would like to know what shift kits you use, how you like it, and how hard it shifts, etc. I assume this is a stock trans with a stock stall converter. Hopefully this will allow me enough time to save and have my TH200 built right. What else can be done to this trans to help it last?

Its going behind a pretty stout 383 stroker. I'll try to keep my foot out of it. I have a big internal cooler, and an external cooler. Thanks!

I can't help you with helping it last, but I have used a cheap B&M shift improver kit in a couple TH350's with good results. One kit went into a junkyard trans then behind a Olds 350 in a friend's 72 Cutlass. We abused that car all through High School and it kept coming back for more. Very easy to install kit as well. It would chirp 2nd AND 3rd gear nearly every time at heavy throttle.

The temporary TH350 in my Malibu is manual valvebody so I am the shift kit. \:\)

Buy the B&M TRANS PAC!!!If you want it to shift HARD(less clutch wear). It is around 70 bucks but WELL worth it.I have used the cheaper B&M plate kit and they are OK for a firm shift but I like mine to screach 2nd AND 3rd.So if you want very hard shifts go with Trans Pac and if you want a FIRM (maybe 2nd gear scratch) go with the B&M Shift Improver Kit( plate kit).I have installed probably around 20-25 kits.I used a Trans Pac in a trans that was slipping 3rd under hard accelleration and it fixed it.I drove the car for 6 months before I sold it.Just my 2 cents.

Jegs shows the transpac for 53.99. I assume thats the right kit. What is involved with installing this kit? Besides uninstall/install of the valvebody? How does it shift under light to normal acceleration? Thanks!

That's the kit! I get mine at my local speed shop most of the time and pay a little more. The usual, remove the v. body, change some springs,remove some check balls, and stack some plates!The biggest thing to NOT do is file your old plate flat. It shows in the directions.I would drop the trans and turn it upside down, BUT thats just me. Dan

Well, its not installed yet so I can put it on an engine stand. I always thought it wouldn't be good to turn the transmission upside down. I'll give it a try when I can get the kit.

Otherwise, keep the suggestions coming. Much appreciated.

I would also check into Trans-Go... I have a Trans-Go in both of my TH-2004Rs and they shift AWESOME
