ok i have this turck that i just got it is a 1991 ctd non i/c getrag g-360 five speed and a 205 t-case i was told it had a new reman transmission ($3,000) and a rebuilt transfer case i got the recipts for all the parts and work from the guy i got it from i bought it wrecked from him it was a fairly light hit in the front end some frame work and new bumper brackets/bumper and a radiator that had to be fixed and just some sheet metal work nothing real bad.. there is the back ground on the tuck


here is the problem it runs and drives perfict except it has a bad vibration at 65 to 70 mph (i think it is the drive shaft) that will be going to the shop to get rebalanced the big thing is with a reman/new transmission i am a little mad it is jamming in 5th gear when i go to down shift it up shifts just fine nice and smooth and down shifts just fine 4-3-2-1 exept if i put it in 5th i can not get it to come back out i have to stop pull the shifter off of the stub shaft and kick it up towards the passenger side dash (ya i know thats bad) then i can get it to row threw the gears easy but just as soon as i am back up and running down the road back to 5th i go and i had to down shift again to turn it did it again it has done this a total of 7 times now just so i could make it back home i drove it in 4th most of the way (slow!!) to get home because i did not want to break the stub off what do you guys think has caused this problem ???? i have found out by accedent that if i pull straight back towards reverse(have to buzz it a lil) it will down shift normal could the 5th gear shift fork inside the trans have gotten bent when he wrecked it ?? altho he drove this truck all the way from kansas to mo and i have drove it about 100 mile before this happened ??????


Thanks Jason

well there ya go dose this truck have a removable trans tunel like the old trucks did (70's-80's)

 

Yup my truck does the same thing..

Here is how I get around it with out buying ot rebuilding tranny.

1st: drain all fluid then fil it bak up but add 1 extra quart threw the PTO top bolt hole on side of tranny. also I used Mobil1 syn oil as the fluid for tranny.

2nd: when I down shift I always pull straight back and not towards myself and for the last 2 months I have had no problems.

I think it is the shift fork wearing out.

I did find that if you do try to downshift and it sticks keep you foot in and push the shifter back into the 5th gear position and then try an down shift .. usually works so that way you can keep driving and not have to stop.

hope this helps

 

well this trans is new/reman so it should not need rebuilt unless something got screwed up in the wreck and it has mobil 1 in it and it is 1 qt over full and when i pull straight back towards reverse i have to pull back so hard it buzzes reverse because when it lets loose of 5th it pops?? out


jason

 

wow sounds like you may more problems then I have....

 

ya it is even worse now it is hard up shifting now all i did was drive up the drive way this moring (long drive way) to see how it was and it is rough and grabby shifting up i pulled the shiter boots off so i could hear the trans and it is amking on hell of a noise it gose clunk when you shift and it has a rattling sound to it real loud i have had 6 trucks with getrag trans and none of them have ever made this noise including the one i blew up and rebuilt my self lol (that was not fun) so i guess iw ill just pull it out of the truck so i can get the top off and have alil look to see what is going on any one got any ideas before i do pull it it is cold and muddy out and i really dont want to pull the thing out

Jason, that tranny should stuill be under warranty. Call the shop( number is on teh reciept) and see where teh nearest Certified Service Shop to you is. I'd bet there is a place in Springfield that will honor that warranty.

 

If the previous owner was in 5th when he crashed it, and his hand was on the shifter.............well there could be broken and bent problems with 5th!

just a thought!

 

Nope, clutch was fully depressed, sliding with locked up brakes......plus that tranny probably has about 500 miles on it plus whatever Swampthing has put on it since the wreck....

 

I'm gonna throw my hat in and put some blame towards the toploader. Part of the 'labor description' said ''shifter assembly'', yet there was no shifter assembly in the parts. I can say that all the shifting problems I had before I rebuilt my tranny (grinding going into 3rd and 5th, popping out of 3rd and 5th) were still there after the rebuild, but when I slapped my core toploader on while I had the tranny out a couple months ago, all the issues went away...

 

I'm with Greg.

 

well that i kind of what my local tranmission shop thinks also like chris said the trans only has 500 from him and about 150 from me so it should not be a problem with the insides i called the shop that built the trans for chris and they said they can not remember if they put a top on it or if they used the old one he said that he thinks they put a "new" used top on it tho

jason

 

JAson, I bought a "new" top end from the classifieds here and they installed it. They reused teh shift fork for third, but the rest was replaced.

 

There was no visable difference between the two that I had---the only reason I put the core in was that since they were so similar, I figured it couldn't get any worse. I wonder if there's a spring missing behind the detent-ball for 5-R, making the ball hang up? Just throwing out guesses...

 

ok thanks i am just going to see what happens when i take it to the trans shop here they are going to call the shop that built it and try to work out warrenty payment to get it fixed that is what your shop said to do when i called them


Jason

 

well the trans is out of the truck and pulled the mian shaft out to get to all of it first off the top is shot it was not letting it fully engage 5th from the start after the rebuild (per the where marks on the gear) and becuase of that it chewed up the 5th gear syncros and the gear its self is junk now and the main idler so it is basicly time for another rebuild !!! because it need new synros bearing and 5th gear along with a new shift fork an idler and some small assorted pieces all in all a grand total of $1,084 and that is with my shop discount as i take all my trans and t-case work to these guys i even take the fire trucks to them if i can not fix the problem so now i have to find out if any of these parts are warented and call the shop again to see if he will do anything which i know he wont as he said he only warenties his work when a customer brings in parts and there is no way to prove that the rebuild was bad altho my shop thinks it was as the main shaft had 30thousandths play on it which is way to much so any one need a getrag lol i think i will be putting in a nv4500
