How to get the tranmission pan unscrewed to change Gasket 1984 chevy c10
If you are going to change the gasket, you should also change the filter at the same time, especially if it hasn't been done recently. You will need a large drain pan to catch oil in because there is no drain plug. Remove the bolts down both sides of the trans pan, 1/2" I believe, and loosen the back ones 3 or 4 turns. Loosen and slowly remove the bolts on the front of the pan because oil will start to drain from there. Once the oil has drained remove the back bolts and drop the pan. clean it out good and check for "stuff". It's normal to see silver filings in the oil but an excessive amount or actual pieces indicate a problem. Two screws should remove the filter. Replace it and put the new gasket on and set the pan in place. Bolt it on. Torque specs for these bolts are 12-13 ft.-lbs for the Turbo 350 and 400. The 700R4 is torqued to 18 ft.-lbs.
If you have trouble getting at the rear bolts on the trans pan, you may need to unbolt the trans mount and lift the tailshaft a little with a jack to get enough room to get it there. Be gentle doing it.Hope this helps.
