Quickie Transmission Refresh

[2002#3]

My current M10 rebuild project will use the 4 speed transmission currently in the recipient car.  The transmission is in good shape.  I want to give the transmission an external refresh before it  is mated to the new engine. 

QUESTION:  Anything I should I consider doing or replacing other than the following? 

• cleaning
• rear, front, and shifter shaft seals
• backup switch
• drain crush washer
• fluid 

I did this 5 years ago and the aforementioned items are all I remember doing/replacing.

 

Thanks,

If you did it all 5 years ago and it's dry, I see no need to do seals again.

Clean it, change fluid and move on to another task

I second that ^

I'll bet Larry meant to say,

 

"I did this to another transmission 5 years ago and the aforementioned items are all I remember doing/replacing."

 

Otherwise, I'll third that.

Yup a quick trip to the quarter car wash to hose her off and install.

You guys are sharp!

 

'76mint is correct.  Yep, I refreshed another transmission 5 years ago ('74 tii) and I am enquiring about a different transmission which is in a '70 2002, works quite well, and has an unknown history.  Best guess:  original ('70).  

 

Sorry, guys, I was not clear.

In that case, seals for sure, if the reverse switch works run it.

Make sure the clutch pivot pin is ok, replace if worn.

I like this GL4 Trans oil, can be found relatively cheap on amazon, Summit Racing, Ebay

Making sure all the shifter/platform bits are in good order,  inspect  that guibo /flex disc is serviceable. and new lock nuts for reattaching it. As tech 71 says fork pivot pin as well.

If you are going to use a pressure washer cover the vent in the top of the case, you don't want to get water into the trans (it is hard to get out without changing the oil 2-3 times)  if it is on the bench change the shift shaft seal while you are there.

Thanks, guys, for the thoughts and suggestions.  Exactly as I thought.

Elbow grease is all you need, plus Purple Power, Scotch Brite pads, small screw driver and patience.

Thanks, Jim.  You are correct.  I did it 5 years ago with your approach to cleaning and with your results.

I wish I had the energy to clean as noted above (those look great).

 

But I don’t, especially after pulling transmissions off the shelf, inspecting and tagging, then loading them into the truck to take to the rebuilder (turning ‘gamblers’ into units I’ll install or sell).

 

Anybody have a part number for an Elring gasket/seal kit for 245 5 speeds? -KB
