Tranny Lube Pump
I have been wanting to build a tranny lube pump for my Geo Storm so I can tow it behind my '79 GMC Motor Home (400 SB). The RV pump that cost about $1k looks like it uses a standard RV water pump which cost about $100. The pumps run on 12 DCV and come in different GPM rates. Other than the pump some 3/8 hoses two valves, a tee fitting and a nipple which needs to be fitted to the trans oil pan will be needed. I will write more when I finish installing and testing the pump. Also you should install a low presure switch and connect it to the cars horn so it will beep if the pump fails.

|Choptop26||That's a great idea . I'm sure I have an old pinion yoke somewhere . That is a nice neat way of securing the bearing caps and the driveshaft . Maybe I can mount the yoke in a way where it can spin freely to avoid breaking anything . Thanks for the idea . Chuck|

|Choptop26||The driveshaft disconnect is interesting . Much more dependable than a pump but still kind of pricey . I'm thinking of mounting a bracket of some sort under the rear of the car where I could just pull the u bolts on the rear u joint and secure the back end of the driveshaft in the bracket to hold it up and out of the way . But still leave the slip yoke stuck into the tranny so I don't lose any fluid or get any contaminants in it . That way I wouldn't have to completely remove the driveshaft and have to find a place to store it and also have to plug the tailshaft too . At least that's the direction I'm leaning until somebody throws a better idea out there .|

I have seen a driveshaft that the RV co's have that diengagies the drive shaft (eliminates removing it)while towing and must be less then the pump.
found it, $750

I got to thinking about it and came to the same conclusion . It's just not worth it . Thanks for the input .

|T-bucket23||Its a lot easier and safer to just pull the drive shaft. if the pump dies and you dont realize it you will be buying a tranny. Not worth the risk|

How to make a tranny lube pump ?
I want to tow my coupe with all four wheels down with a tow bar . It is a small block chevy with a 350 TH automatic and a nine inch Ford rearend . Looking around on some of the RV boards I've seen that they install a fluid circulating pump on the transmission and tow it in neutral with no damage . That sounds good to me but the pumps they sell cost around $1K and that just ain't in the budget . I know there are some very sharp tranny guys on here that could probably tell me how to make my own system for cheap . Like what kind of pump to use and how to plumb it in . How many gallons per minute/hour it needs to flow etc. etc. Maybe where to get one . Thanks in advance guys .
