Going to rebuild trans, what kind of stall should be used?

[Crispy]

My transmission decided to go out on me the other day. I'm going to get it rebuilt locally and was thinking about going high performance. I was told they would use heavy duty bands, a shift kit and a vette servo. Also gonna add an aux. cooler, temp gauge, and deeper pan.

Is there a preferred shift kit?
I'd like to add a higher stall speed converter while im in there, the trucks engine is stock besides a K&N filter and a flowmaster cat back. I do plan on doing some valvetrain work in the future as well as full length headers. What kind of stall speed should I work with?

Thanks, any and all input is appreciated.

edit: upon further research I found a TCI rebuild kit that says it improves shifts as well. So shift kit + rebuild kit or is a rebuild kit enough?

It all depends on what you are going to do with the truck. The vette servo is good & the shift kit can be a mild one (TCI, B&M, etc...) to a Transgo HD2 kit.

Are you going to do the other upgrades?

- beast sunshell
- GM 5 pinion planetary
- upgraded sprags

Keep in mind this would be a mildly built tranny. If you want to see big dollar builds check out FLT or Perfomabuilt for their build lists & compare with your builder for his advice.

Very familiar with Performabuilt, I've had a few auto F-bodies. Basically what I want is reliability for everyday use and occasional hauling. I'm not trying to build a ground pounding street truck. Honestly I'm not sure what the other upgrades would bring me. The builder didnt mention anything about the items you mentioned. I told him i need a tranny that will tow, and I want to firm up the shifts some.

I went with a Superior shift correction kit, same as the Trans Go unit. If you want performance, go with a performance convertor. If you want to tow, go with a towing convertor. They are two different beasts.

A shift kit is usually lower priced add-on, what you want is one that is going to be installed while it's apart, it's a little different and addresses stuff that wouldn't be addressed during a simple bolt on in your driveway.

The 5 pinion planetary rear set is a good upgrade, the front pinion is ALOT of $$$ though ...

look into a Yank TT3000 stall...i got one in my truck when i built my trans...it is great for daily driving as well as towing, plus the performance side of it is pretty decent as well

A 3000 RPM stall used for towing?? What are you towing??

There is more to a higher stall than just the space between the stator and the turbine. Technology has come a long ways in getting the most out of a TC.

I have a 4,200 rpm stall in my hoe. It acts like a stock TC until I run it up against the “transmission brake”. The TC also has a multiple disc’s for the “lock up” which I have set for 33 mph.

The higher the stall, the higher the torque is multiplied going into the trans.

I have used Midwest Performance Converter’s for many years now. They make high tech quality converters for a good price.

They have a list of questions on their web site that allows them to accurately build the specific stall TC for your application.

Expect to spend around a thousand dollars for a high quality, lock-up, TC. It will be worth the few hundred dollars you spend over the cheap imitations.

The torque converter is the only part of a tranny rebuild which can actually ADD Noticeable performance. The shift kits and all will make is shift harder but the TC can actually make it “faster”.

Just my two cents worth……….

Everything 95twinntt said is correct x910341390341294710324712. Beware of wasting your money on parts that will only make your tranny shift harder. Your not gonna make your tranny "better" or "smoother" shifting. Stall converters are where its at and don't just go out and buy one do some hardcore research for your particular vehicle / driving habits.
I find the stock stall very desirable.

its not a big stall at all..around town its tight as hell..it works great for towing since it puts the motor right in the power band when taking off..it locks at highway speed so its not much different then stock..plus performance when you arnt towing.
