Hey all,

I’ve got a 1962 dodge lancer with what I believe to be a push button 904 transmission. The car belongs to a friend of mine and they’ve asked me to look at a transmission leak. Last time I worked on this car (been a few years) I remember it having what I thought to be a pan gasket leak.

I’ll go over there this weekend with a pan gasket and see if that’s it. What kind of transmission fluid should this car take? Is the fluid level checked with the car running in park?

thanks

I think pretty much all automatics you check fluid in neutral. This is because the fluid flow path is different. Same deal if you have a 'verter leak down problem. You start it and run it in neutral and the converter will refill quickly
 
Another common leak is the dip stick tube "o" ring. Can look like a pan leak because it will leak on to the pain rail area. Nice looking Lancer.

Is there a place I can buy a seal kit for the most common leaks? Like the dipstick, shift selector shaft, etc.
 
I used to get all my parts from Pat Blais.
Not sure if he is still in business.
Sorry to hear it's from a late friend.

You can get a "seal up kit"..but some brands don't even have front and rear seals, and they usually have the cheap pan gasket.
 
Pat replied, he is still in business and can supply the needed seals upon request. I'll take a look at the car this weekend and hopefully I will be able to pinpoint the transmission leak.
 
You can use Ford Type F, although I don't know why. The factory called for Dexron.

Ford type "F" has a higher coefficient of friction, then dexron. Back in the day, when Dexron first came out, there were problems of Fords having trans failures. The fluid manufactures, sent out a tech bulletin that said it was OK to use type "F" in vehicles, that called for dexron, but not to use Dexron in vehicles that called for type "F". Dexron would cause the Ford clutches to slip and eventually burn up.

Yes, I am familiar with that and have used it in GM and Mopar transmissions before. It firms up the shift a little. But it's not really necessary, was all I was sayin.
 
Type F has a microscopic abrasive that makes the valves in a Ford self-cleaning. It's needed because Ford didn't use filters; only screens. Steel valve bodies can take the trash a lot easier than aluminum valve bodies because metal particles only scratch grooves in the valve bores, but in aluminum, the particles plow a furrow; not removing any aluminum; but instead, raising the metal on both sides of the groove; effectively making the bore smaller; sticking the valve.
 
And I see the fiber gasket for 6.05 free ship..Don't use a cork or rubber or neoprene pan gasket. Red or black fiber only.
 
I’ve got around to looking at the car. The only wet areas I see on the transmission are the pan rails and towards the rear of the transmission.

Well... I lowered the car back down. And figured I should drive it around so that it might make the trans leak more apparent. After a few failed start attempts, I’m thinking the fuel pump went out. Of course
 
I think those transmissions leaked new on the showroom floor.
