Dan Dishon's Transmission Den / Re: PG Racing Band Ajustment

« on: August 18, 2017, 08:13:58 PM »

72 inch pounds then out 3 1/2 turns. If it's a new build using a new band, I like to re-adjust after 3 to 5 runs. If its a freshen-up where the band was re-used, or a relined band, I say once at 50 passes, then you should be good for the season. We do a lot of bracket racing and put around 300 passes on a year. I can say at the end of the season the band is still spot on. The key to long band life is running a good dual ring servo. One with a lip seal, or 2 steel rings work the best.

How old is the solenoid? Solenoids do get dirty and as they warm up from use throught out the night. This can cause them to drag on release and apply. And when you are talking hundreds of a second you won't notice it on apply because you are not timing the apply. The BTE non pro brake is a very basic unit, and not prone to valve sticking. Something else the needs to be checked is piston to case clearance, just like a piston in bore of a block, if it is too much the piston will rock in the bore and could drag on release. Any of these problems will not only show in rt but will show in your 60ft. I had an issue like this and found it to be uneven spring pressure on the release spring of the reverse piston. 6 of the springs were 30% less at installed height and all were on the same side. I found the by watching the piston as I slowly applied the piston with air. Keep us up on your progress.

I have used Transpecialties for years, many of my customers also run their converters. I believe any of the top manufacturers are going to do you a good job. The key to getting it right the first time is giving accurate performance data. Who ever you choose be sure to give as much data as possible. It's more than just on track data, be sure to include as much data on your engine as possible.

Its not very often your trans actually pukes out anything, only if it gets very hot, or breaks a converter. So checking wouldn't have to be done on every warm up. The problem I see with the check valve is it would not let the trans breath back in after cooling off. The vent on a trans is there to let air escape as it warms up and expands, so the air would need to be able to return. I would just move the trans catch tank to the rear of the car, this would get it out of your way, and if something were to happen and you puked so much ot overfilled it would all be behind the tires.

Agreed, spinning parts and no pump pressure is never good. How ever for a plug check it's a trade off that needs done. Definitely not something that sould be done often.

Common practice it to put it in neutral at the finish line. This gives a clean release of the high cluch. Killing the motor in gear leaves you with a release caused by the pressure loss as the engine shuts down, this causes a drag on release. Not sure hoe many times this would have to be done to cause clutch damage, but better safe than sorry, put it in neutral first.

Yes is normal, it is the drag of the high clutch. The more clutches you have in high the more the drag you will have. There is only so much space in the drum, so more clutches means less gap between the clutches resulting in more drag. As long as it doesn't take much brake to stop the wheels from moving you should be fine.

Dan Dishon's Transmission Den / Re: QUESTION ABOUT CONVERTERS

« on: May 15, 2017, 10:16:00 AM »

A loose converter gives you a good 60ft but not so good mph for the et. When I switched my Roadster from 6600 down to 5800, I lost .02 in 60ft but my et was the same and my mph picked up almost 3. Im thinking the converter may be too tight, keeping the motor from getting into the power band of the camshaft. A tight conveter will have better mph than the et shows, your mph is more online with a 5.40ish et.

Have you stall checked this converter?

Most hold between 6 and 10, deep pan, no cooler, and an 8 inch converter 6 to 7.
No as far as what fluid to use. That is a good question. I personally use NAPA type f, but ask 10 people and get 10 different answers. I run large coolers with fans on both my cars, that help with fluid life. I know some cars just dont have the room for a cooler, so in that situation I would run a synthetic fluid.

I see a lot of racing units a year, with a variety of fluids used, from the cheapest thing that can be bought, to hydraulic fluid, to the most expensive, trick fluid on the market. None show anymore wear than the others, now as far as performance goes, only testing will tell you if one fluid is better for you over another.

my rule of thumb is like all fluids, if you change them on a regular basis you should have no problems.

3/16 is max, definitely go with a thicker spacer to get to or under the 3/16 gap.

« on: April 05, 2017, 07:46:28 PM »

Ok you have .035 gap with a .060 spacer for a total or .095? 1/8 to 3/16 is .125 to .187. This would put you .030 to tight. Are there spacers welded to your converter?

« on: March 27, 2017, 05:56:21 PM »

We did a light weight glide for a customer 2 years ago and found the TSI case was lightest by a pound over a Reid. Down side is TSI cases are on back order with no estimated restock date. The results of the light weight build was 22# this was a TSI case, fabbed aluminum pan, hipster aluminum valvebody, TCS aluminum pump, and a Coan aluminum hybrid drum. Compaired to a JW set up with all steel parts and cast pan.

Agreed not worth the hassle to send in, they will do it, you will have to call them to start the process.
