John deere tractor will not go into gear

I have a john deere 4010 that wants to grind going into gear immediatly following the use of the loader. It has zero problems if you just start it up and go, but if you touch the loader such as mashing a brush pile and then wish to place in reverse, you have to give it several minutes or put it in park and restart and then you can go. I just had the front pump rebuilt and I'm thinking it has something to do with not having enough hydraulic fluid returning to the resevoir, but I could be wrong. Help please.
 
It"s a row crop 1962. I"ve only had it since November and the only time I got to use it, I blew the seal out of the front pump. Didn"t use it much, but didn"t have any troubles with transmission until I got it back from dealer. Can a faulty/plugged valve in the front pump keep fluid from returning to resevoir properly? and therefore shorting the transmission pump of needed fluid?
 
It has a John Deere 720 Loader on it with a joystick. I bought it this way, but all of the loader valves are in front and below the brakes like new tractors. It only has one set of scv's on it and they don't currently have anything plugged into them however, they were reworked at the same time as loader.
 

When one depresses the traction clutch pedal the trans pump stops turning(pumping hyd oil). that is the connection between the traction clutch & the hyd system on a '62 4010
 
What are your reconmendations for resolving this. Is it a problem with the transmission pump? Clutch? or did something get installed wrong when the front pump was rebuilt?
 

Frt hyd pump and trans have little to nothing in common. I'd call frt pump work & then trans shifing problem a coincidence back when I was a JD dealer service manager. I've seen that coincidence many times when a tractor was brought into the shop for an engine overhaul send it home and the trans or differential failed. Customer always thought engine overhaul caused other failure. NOPE COINCIDENCE
 
Where is the return line for the loader?? in needs to be going back to the filter housing.. or back into the return circuit.. (normally the filter housing is the easiest place to go..) That will help with you losing your oil..
The problem is the transmission pump is about half the GPM as the front pump.. so the return oil needs to go back to the filter housing.. (bypassing the transmission pump.)

A 720 loader on a 4010... A really nice loader.. worth as much as the tractor..

TXJim... What dealer were you the service Manager at.. and when.. Just curious...

I was employed at Farmers Impl, Co in Cleburne from '66 - '87 which sometime in the 70's was incorporated into T W Bailey Jr. & Sons. I ran a JD service center in Alvarado that belonged to the corporation from '75-'85 and was transferred to Cleburne to be that stores service manager in '85 until late '87. Then I decided to begin a custom hay baling business and went out on my own
 
(quoted from post at 14:54:09 03/25/13) So if the transmission pump is the only thing in common between the shifting and operating the bucket is this my likely culprit?

The trans pump oils the trans gears & shafts plus supplies oil to frt hyd pump. It's possible that depressing foot clutch pedal could cut down on lubrication causing hard shifting of syncronizers(but I've never personally witnessed this condition). Another possibility is worn syncronizers &/or shifting components. It also could be a traction clutch with incorrect free travel setting or a warped clutch plate BUT I still stand by that the problem isn't related to the frt hyd pump or it's prior repair.
 
There "should" be NO relation between the loader operation and the shifting of a 4010, you have ether got a clutch issue,,or bad sychronizers....
 
I Just want to locate the problem to fix not point fingers, but I can physically use this tractor for long periods of time with zero shifting problems until the front loader is adjusted. I'll give the mechanic a call and have him pull the floor plate and look into the transmission and see what he sees. I have a feeling he might find a bad synconizer or one that is starting to wear. If everything looks to be in working order, it's time to evaluate my hydraulic preasure and fluid levels because the dealer did not refil this which means they probably didn't flush the lines and or change the hydraulic filter. I'll look at my paperwork, but i'm pretty sure it wasn't done. Thank you for your help. I'll try to post a reply when we find the problem.
 
I bought the tractor for the loader more or less. The loader prices new for what I paid for the entire package. (tractor, loader, duels, bale spike, and soft umbrella all for $11,000) I am completly ok with putting a few thousand into this because it will be super nice when everything works as it should.

Plus all the paperwork came with for everything ever done to it. When it was overhauled to when a steering valve was replaced all by dealer. Even the origional purchase agreement for it's warranty. Super cool.

My mechanic is retired John Deere thirty plus years and worked for IH before that so if it's clutch or transmission, he will find it. He was baffled when I told him what it was doing. He's going to look at it this week. Hopefully I'll know something more in a few days.

It's definitely easier to diagnose a problem in person than over the internet. God luck with your mechanics diagnoses.
 
Yeah. Good old John Deere. My wife went to work for them almost seven years ago. Fabulous company to work for. They have been really good to us. But working for them, we have relocated, and the closest I've been to my property since has been about a four hour drive. I can't afford land in Iowa, so i'm keeping my little patch of heaven in Missouri. Right now we are in Davenport and my farm is seven hours southwest of here.

Lots of faith in my mechanic. He has kept my gas tractor running for seven plus years through everything from a busted crankshaft bearing to kids rearanging my plug wires(loved that one) he will find it. I'm just trying to help from off location. :)

Thanks for everyone's help.
 
Kasey... Good to hear... almost 15 yrs here.. plus a few more at a dealer before that... I've been lucky.. (or maybe unlucky)... I've stayed close to home for those 15...
I'm going to take a wild Guess.. and say that your wife is Mary... haha..
