I just installed my gear vendors unit and had a new driveshaft made with 1350 series ujoints. I'm getting a vibration which I assume is from my angles. Currently my transmission is 3* down, pinion is 3* up with a driveshaft angle of 1.5*. Car is sitting level at ride height. I have SS springs...

I had an issue earlier with shifting but it was misadjusted bands. So I was gonna move ahead with my transgo tf-3 install but my valve body doesn't look stock like everyone elses. What do you guys think? Along with the kit I was going to remove the accumulator spring for firmer shift and use...

I have been trying to set this up myself. Right now I have the stock shim under the big bearing no shim on the small bearing just snugged the nut for some bearing preload for gear mesh purposes. I have about .007 backlash at 3 spots. I attached some pics for the pattern. Is it acceptable? The...

It feels like its binding between shifts. Could it be a sprag? I haven't broken anything. Or could the bands be out of adjustment? I just dropped the transmission a few weeks ago to install a higher stall converter. Now this issue has risin

Evidently nobody in my area sets up ring and pinions anymore, so I'll have to try and do it myself. Can anyone offer any tips on setup like torque specs. It's for a 742 case. New Richmond 4:10 gears new suregrip from doctor diff. Thanks

I am in the process of gathering parts to rebuild my 742 case. I have 4:10 gears and the install kit. What should I get for the carrier? Locker, suregrip, suretrac, etc... It's a summer car that will be at the dragway 6-12 times a summer with slicks. I currently run 12.4 @ 110 in the 1/4 with...

Do you guys recommend a beginner putting new gears in. I have done other stuff like install a crank and bearings, valve body mods. just never tackled a rear gear. Any write ups you could point me towards. I want to do this over the winter. Thanks

I was checking my ujoint and when I was pushing up and down on the driveshaft I noticed there was some play maybe 1/8" up and down. Is this normal or is the trans. Toast?

I have an opportunity to grab an A904 for short money. The owner said it was rebuilt but never ran. he said its been sitting for 5 years unused and just wants to get rid of it. You think its worth grabbing for $200. Is there anything i can look for before i install it or do i need to crack it...

So I've been driving my car around town trying to work out all the bugs since putting it back together. I have a Lokar kick down cable on it adjusted to there specs. What i don't understand is why the car wont shift into 3rd until 60 mph. Is this normal? It's a 70 dart swinger with magnum...

So stupid me left the Transmission slip yoke exposed to the elements by accident now the outside of the yoke is rusted. Am I going to need a new one or could i sand off the rust and reuse this one? Tom

I bought a very low mileage used transmission off a guy who said it was a reverse manual valve body TCI unit A904. Is there anyway to tell if it is indeed a manual valvebody without driving it first, The pan is off right now because im replacing the filter and gasket and adding a magnet to the...
