I see the TF1 as a street kit and the TF2 as a full race. http://www.summitracing.com/compare.aspxWhy would I want a race shift for a street car that may see the track 1-2 times a year? Just looking for some input. Don't want a car that is uncomfortable to ride in. The wife and kids will be in it.

my bad..CRT may not do lock up trannys
try your local tranz shop for rebuild kit and a reman TC
Try calling CRT for a price on a l/u trans. I called about one for my '85 Ram p/u & iirc he quoted me $600. Can't remember the price for the converter, tho. These guys have the 904 l/u converters in different stall speeds http://www.transmissioncenter.net/dodge.htm .

you can block the loc-up valve on the VB and get a reman TC with the guts left out to make it non loc-up(or just block the loc-up valve) with out changing the input shaft you will need a smaller 904 slip yoke as the od 833 use a large slip yoke like a 727 IMO,just a rebuild and block the loc-up valve and run the TC thats in it should be the HD a999 if it a police car tranz,IIRC

Another option is to modify the lockup valve to engage at 40mph instead of 30 so there is a little bit less torque at lockup. There was a TSB on these transmissions for shudder. The Transgo kits do modify the lock up valve body but does not have the substitute spring for the valve. There is a cheap 20 dollar shift kit out there that does have a new spring. I used the spring and tossed the other stuff but kept the nifty drill bits. I do not have any road experience yet with this lashup as my engine is not yet complete. Just threw this out for something else to worry or think about! The rebuild kit I used was an Alto Red kit with Kolene steels. Craig

I just went and looked at the TC that I got with the 904 I have. It has a sticker on it that says
HS LOCK UP
Is this a high stall l/u? I will try to post the trans numbers later today. Thanks for the help
edit: I looked at the numbers and this is what i got. The first 2 were not stamped really well, but this is the best I could do.
PK4295887X 7656 9964
If you could help me find what I have to work with, I would appreciate it.
