im new to adding fluid to the transmission. it was rebuilt, and torque converter has fluid. my question is this ... before I introduce 5 or so quarts of fluid, can someone check me and tell me all the places fluid can come out, so I can verify the holes are plugged? there is a modulator present, pan has all the bolts, stick and its holder have the rubber ring on them, speedo cable and housing in place. am I missing some obscure hole somewhere where all my fluid will sneak out over night?

thanks... heres the answers

Is the Trans in a vehicle with TC/TorqueConverter & DS/DriveShaft connected?
Detent Cable Hole, Front & Rear seal.

Yes, the rebuilt trans is in the vehicle and connected to the newly rebuilt 350. There is a TC. The driveshaft is not in place. At the end of the th350, ive got just the geared end, no yoke.

I didnt put the two together so ill check on front and rear seals. I would certainly hope to go to that much trouble they put the seals in, but ive seen crazier stuff. detent hole???? wheres it at and ill check.

I'm assuming you mean, Gear = splined Output Shaft.
The rear Seal is in the Tailhousing. When the Yoke is slid in it seals against it.

Did you install the TC correctly?
Turning & pushing, should feel/hear 3-clicks, Input Shaft splines, Stator Splines and Pump splines/lugs.
Should have 1/8" to 3/16" between the Flexplate & TC before slidng the TC forward to bolt to the Flexplate. If not the Pump Gears can be damaged/broken.

I didnt install the trans or rebuild it. it was done and bolted to the engine when I got the project. if the rear seal is inside the long tailhousing, I cant see it. I will check when I get home and see if it looks like theres anything in there. I do have a splined output shaft present and sticking out. I did not install the TC.

Just so I can get on the same page, Is the tranny leaking overnight? or are you just replaceing all the gaskets and seals to be sure it doesn't happen? :confused:
