Young Ed Posted July 1, 2021 Report Share Posted July 1, 2021 On my to do list for summer is to seal up my overdrive in my P15. It leaks pretty bad after a drive. From what I saw last time I drove it's coming from up front some where. The drips form on the raised area where the drain is and are coming from in front of that (not from the side like the drain is lose or something). So to prep looking for ideas on making something to safely lift it in and out with a floor jack. Quote Link to comment Share on other sites More sharing options...

plyroadking Posted July 1, 2021 Report Share Posted July 1, 2021 I don't think they'd fit nicely on a standard tranny jack. I just jack the car up fairly high and then slide them out or in while laying on my back. Quote Link to comment Share on other sites More sharing options...

I believe last time I put it in with a 2x6 and a ratchet strap but I'd like to make something a little more stable. Quote Link to comment Share on other sites More sharing options...
greg g Posted July 1, 2021 Report Share Posted July 1, 2021 I found it helpful to jack up both ends of the car to the same height. Do you have the tunnel sheet metal section out of the floor? Have you assured the OD input shaft has the same number of splines as the original trans? Are you planning to utilize guide bolts? Guide bolts a 3 0r 4 inch long bolts from the hardware store with the heads cut off. Screwing two or three into the bell housing that will assist to slide the trans in place along their length. After you cut the heads off, cut a slot 8n the outer end 5o accommodate a screwdriver to aid in removal. I used Allen head cap screws to replace the stock bolts as it was more accurate to get the threads started into the bel housing. The fdrivers side upper can be a pain in the butterfly to get aligned even with a six point socket. The Allen head is just that much more precise which gets it started much easier. 1 Quote Link to comment Share on other sites More sharing options...

Overdrive is already in the car. Been running it for years. Just tired of jacking the car up every month or so to refill the trans and don't want to ruin it if I get too low. Not to mention the constant oil spots all over. Yes I should still have the guide bolts from last time and I will pull the floor even though it's a pain.

Merle Coggins Posted July 1, 2021 Report Share Posted July 1, 2021 Most floor jacks have a removeable saddle. You can get an adapter, like in the following link, to convert it to a transmission jack. https://www.amazon.com/Shop-Tek-Transmission-Adapter-Passenger-Light/dp/B00BJ9X7OW/ref=asc_df_B00BJ9X7OW?tag=bingshoppinga-20&linkCode=df0&hvadid=80608001419900&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=&hvtargid=pla-4584207578840646&psc=1 1 Quote Link to comment Share on other sites More sharing options...
Sam Buchanan Posted July 1, 2021 Report Share Posted July 1, 2021 While the tranny jacks and adapters are great tools it is possible to scratch build a cradle that will make it easier to manage the tranny. Below is the really crude and ugly cradle I use for jacking the non-OD trans in my P-15. Prior to removing the transmission I moved the floor jack under the trans and used whatever scraps of lumber was necessary to fit the contours of the housing so it would balance on the jack. Yep...it looks dreadful but actually works quite well. And of course the guide pins, in this case flats were ground so a small wrench could be used. 1 Quote Link to comment Share on other sites More sharing options...

Los_Control Posted July 2, 2021 Report Share Posted July 2, 2021 A little hokey but works. I would lay plywood down in a gravel driveway. Then pipe and plywood to roll it with. set the transmission on the rolling plywood. Then play jenga and start adding blocks under the trans to get the height you need, Be safe! then set the correct angle to match the motor. Takes time. When you finally get exactly what you want, just roll it into place. You would not want to get it close then try to manhandle it in the rest of the way .... you might lose it all and drop it. You really need to be patient and get it spot on and then just roll it in. Did the C6 in my Ford 1 ton a few years ago like this, many years ago the 4 spd in my 1960 Dodge 1 ton. Pretty sure I might cry if I try to remember how I did the trans/transfer case in the CJ5 ? ? ? Quote Link to comment Share on other sites More sharing options...

Whenever a ship would come in they would rest on pillars, the pillars where just concrete blocks that were topped with a wooden cradle cut to fit the keel. With that in mind consider this A trans jack, or adapter, has a tilt function built in. Maybe you can make some wooden cradles, some 2x6's cut to fit the trans for example, to bolt to the adapter and use ratchet straps to hold the trans to the adapter. Best of both worlds, custom fit to the trans but more flexible to install? Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted July 2, 2021 Report Share Posted July 2, 2021 Harbor Freight transmission jack at an M5 transmission, several years ago. The strap held the transmission from rolling off. I think the angle of the white top plate was adjustable. The transmission handled better with the solenoid and governor removed (and their openings taped shut).

Merle Coggins Posted July 3, 2021 Report Share Posted July 3, 2021 When I pulled my trans, many years ago, I used my motorcycle jack with some strategically placed 2x4s all screwed together. It worked pretty good. 2 Quote Link to comment Share on other sites More sharing options...
John Reddie Posted July 3, 2021 Report Share Posted July 3, 2021 Ed, just curious, is it this the same overdrive unit you are now using? I saved this photo you posted of the removal at French Lake.

John Reddie Posted July 3, 2021 Report Share Posted July 3, 2021 Thanks Ed for your response. Yards like that are pretty much history here in MA. I sure miss them. Many a Saturday I spent salvaging parts for my cars. John R Quote Link to comment Share on other sites More sharing options...
rallyace Posted July 4, 2021 Report Share Posted July 4, 2021 I used a Harbor Fright trans jack that I borrowed from Greg G. We had to use some wedges and wood blocks to square it up but it worked fine. To do it again I would take the time to build a better and stronger wood cradle to hold the trans level on the jack.

Young Ed Posted August 13, 2021 Author Report Share Posted August 13, 2021 Leak has gotten worse. Ready to pull this and dig in. From what I can it's leaking down the front and the drips form where the drain is for the front section. I do have the gasket between trans and bellhousing. Beyond that and the gasket for the input shaft what else can leak? Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted August 13, 2021 Report Share Posted August 13, 2021 If you continue to ignore it the oil leak will eventually stop (when it runs out of oil) ?? Quote Link to comment Share on other sites More sharing options...
Young Ed Posted August 14, 2021 Author Report Share Posted August 14, 2021 Well Merle not much oil came out when we drained it. Trans is pulled and it appears the gasket behind the input shaft retainer failed at the bottom. Also the 3 bolts weren't very tight. Looks like new gasket and a new bellhousing to trans gasket and I'll be good. Quote Link to comment Share on other sites More sharing options...

If those seals failed and disappeared that could explain why the bolts were loose. Edited August 15, 2021 by Sam Buchanan Quote Link to comment Share on other sites More sharing options...

Young Ed Posted August 15, 2021 Author Report Share Posted August 15, 2021 For better or worse the dead is done. Replaced the input retainer gasket and trans to bell gasket. Happened to have bought a trans gasket set off eBay way back and it turned out to have the proper thickness gasket for the input. Luckily I read the manual before just grabbing one and jamming it back together. Per the manual I also filed a slight high spot off the inside the input that leads down to the drain. The homemade trans cradle was working great until I lowered the jack too far and the pressure of the hook of a ratchet strap against the jack popped a weld. Not the easiest too see but the bottom has a clear trail of oil. Trans on the cradle. And the only casualty - my helper misunderstood my directions and shortened my OD cable by what was on the bolt. Hopefully I can remove a little bit of the outer cable and make it still work. Quote Link to comment Share on other sites More sharing options...
