How to put trans lube back into the gearbox
 

O.K. I order a gallon of Swepco 201 from Pelican, brought a 17mm hex socket, test to see if I could loosen the fill screw before draining the oil out of the trans. I am going to change the oil next week, so I am looking for advice on what's the best way to put Swepco into the trans?

In the past I have use a suction gun to suck the gear oil from the container and squirt it into the trans or rig a line and funnel and pour it back into the trans. On my Lotus or other cars.

Since I can get a line from the top of the engine back to the trans the only alternative I see is the suction gun. How do you put gear oil back into the trans?

They sell hand pumps for a few bucks at parts stores. A good tip is to let the Swepco bottle sit in the sun for a few hours to warm up. It'll save you a lot of pumping effort that way.

I used a cheap $5.00 suction pump I bought at Pep Boys. It takes quite a while and I can assure you you will get a workout but the cheap pump method works pretty well.

I just did mine last week & bought a cheap gear oil pump that screws on the bottle. Problem was the threads were to big so it didn't fit tight on the bottle. It still worked but was a bit of a messy PITA. Next time I'll get a better pump that I know fits on the bottle.

Gravity get the car up on stands, run a clear 2m(5-6')x20mm(3/4") tube into the fill, put a funnel in the end of the tube, hang the funnel fromthe rafters or whatever, pour the swepco into the funnel. A hot day helps.

Papers to absorb any spill also help.

What about a cheap garden sprayer?The type that you can pump up,you may have to take the nozzle off because gear oil is thicker than most bug sprays but other than that it should work fine,pour in the proper amount of gear oil,insert the end of the wand into the fill hole,press the trigger and voila!!! it should fill the tranny,you might have to stop and pump up the pressure once or twice but should be a heck of a lot easier than these pumps that you have to keep pumping!! You might even hold the trigger in the on position with a zip tie so you can sit back and enjoy a cold one while the pump does the work.

If you don't have a pump just put some hose on the nozzle cap of the bottle (assuming that Swepco comes with a nozzle cap) and squeeze it in.

I have filled many a transmission and transaxle this way.

gravity is the cleanest, less agravitating, and simplest method, IMO.

I must be doing something wrong then Ronnie. Every time I try some new method of gravity feeding, I end up with an EPA reportable spill:p .

That's the way I do it. But remind me not to change the tranny fluid in both my car's, and my brother's Giah in the same day again, because my arm was about broke off.

I'm with Verburg. The irresistible force of gravity works just fine.

My Swepco didn't come with the nozzle cap, but I had another. So, I transfered the lube into the smaller container and squeezed it thru the clear tube into the tranny. The advatage I see is that you can see when it is full. Some guys already know exactly how much to put into the funnel tied to the rafters. Some guys like me don't. So we need to check. My 901 took all but about an inch in the Swepco container.

Congradulations. I'm glad to see my suggestion won as the easiest to implement.

Its good exercise for the hands too. :D

Follow Bill Verburg's advice, by far the easiest solution.

Gravity plus heat.

There's a great suggestion/article in this months European Car magazine (Tool of the Month). Use compressed air (low pressure) from a compressor to force the fluid from the container through a filler tube.

I thought it was an elegant solution (simple yet ingenious). They even give directions and components needed to build your own inexpensive "rig" from Home Depot sourced components.

HTH,

Harbor Freight has a nice hand pump for about $10. One PVC hose goes in the supply bottle; the other into the filler hole. A few suck/pumps and you're done. Minimal waste and wetness on the driveway.

How does one stop gravity flow when the gearbox is full? Is this a one-person operation? I prefer using gravity to bleed my brakes.

Another way to put the fluid in easily is to use a large 60 cc syringe or a turkey baster. Suck the fluid out from the container with the syringe and transfer it into the transmission. No muss, no fuss.

Those annoying 1 qt. bottles with the mustard spout are no good and I believe that's all Mobil 1 comes in. I borrowed a hand pump, poured four qts. into an old Swepco bottle and it was a very easy job. Of course, when you have a lift, it's really a cinch. I think I was done in under 15 min. from the time I had the car raised.
