I took my trans out the other day to put a new front seal and a new pan gasket in. Put it back in and now it will not go in to gear. All I have is rev. and I get that when I put it in D2. All the linkage is correct and the fluid is at its proper level. Its a 3 speed merc o matic. Is it worth rebuilding or should i swap it out with something else. If its a swap out what will bolt up with the same bell housing? Or is it worth rebuilding.
Was the transmission behaving before the removal? What year Mercomatic is it? If it is 61 up, then it has vacuum modulator. Is that connected? Another thing is the torque converter is not seated or something. This is a weird one. Nothing should have happened to the transmission from what you said. Did you seal the linkage up by any chance?
No it shifted fine before.I took it out because I thought the torque converter was leaking but it was the front seal no big deal thats fixed.Also while I had it out the pan was leaking so i did that too.Well the pan is still leaking and now it will not go in to gear.There is nothing to seal with the linkage.Im going to drain it AGAIN and try to seal the pan AGAIN and see if it fixes it self. If not ill pull it AGAIN and have it rebuilt. Its out of a 54 no vacuum and its bolted all the way in so the torque should be seated.
If you didn't seat the torque converter carefully all the way into the transmission before you installed the transmission back into the car, then you could have mangled the pump.
If you have reverse the pump is working so the torque converter is probably engaged in the pump. Did the transmission have a bunch of miles on it? If so I seen this when I worked in a trans shop. Occasionally when someone would bring one in for those fluid and filter change specials the trans would have 120,000 or more and never been touched. What happens is the clutches have worn and the fine particles of the friction material are mixed in the fluid and allow the transmission to work ok until the fluid (with friction material) is drained and replaced with clean fluid. Pulled trans out replaced clutches in an overhaul and they worked great after that. I won't change the fluid on one now if it's real old and/or high mileage. Some folks may say I'm full of **** but it happens. Thats weird though that it goes in reverse when putting it in 2nd, I would check the spool valve in VB.
Drop the pan & make sure the manual valve in the valvebody is lined up with the inside linkage. Sometimes when you have the trans out of the car and push the outside lever past Park, it will drop the manual valve out of position.
After looking at a spare trans I have it looks like the valve jumped a tooth.It should be between the 1st and 2nd tooth. how do i put it back with out damageing any thing else.
O.K. got the valve seated correct and got the pan back on. Got to wait a day for the permatex to set up and Ill see what happens>
Glad to hear you got it fiqured out. I would not use "permatex" and a gasket. Just a good quality cork gasket is best. Or they make a silicone sealer that you can use instead of the cork. But dont use both. The gasket will slide or mush out and then leak.
Still sounds weird as DR is two positions from Reverse. Good luck, and BTW, I try and use a cork gasket and seal only the pan side. This allows the gasket to adhere to the pan, but not to the case.
Got rev d1 and d2 not sure if it shifts to 3rd but Im sure it will. wwillammc you called it. Thanks for everyones help.
You sure that is a Merc-O-Matic and not what Mercury called Multi-drive. The Merc-O-Matic is a single range transmission with only one DR position. Ah, who cares, they are just BW transmissions.
