i got a used transmission installed in my truck. the only problem is i only have park, reverse and neutral. the tranny was suppose to be good but i was wondering if if is the tranny for sure or if there is anything else that would cause this problem

 

when you shift into the forward gears, do you feel the shifter stop in each gear, or does it stop at neutral? it could be the linkage off.

 

i checked all that it is a little loose but i tightened it all up. it will stop in selected forward gears but wont move. it feels like it tries to engage but doesnt

 

vacuum line to modulator hooked up, plenty of fluid, clean filter? did you let tranny run at idle for 20 minutes or so? if trans was empty when put in, it might take a bit for pump to fill the entire system. converter will suck up alot of fluid, plus cooler lines, rest of system.

 

i added to the level that was in there. it might need more i will have to check again but do you know exactly how many vacuum lines there is? also i will have to check the filter

 

typically only one. it runs into a small canister. should be easy to see. if memory serves, it's towards the back of tranny, canister about 2 maybe 2 1/2 inches. if you're not sure about the condition of filter, i'd definetely change it out. filter kit cheap. comes with filter and gasket usually. good luck, keep us updated.

 

ok well everything is hooked up so hopefully it is just the filter or low in fluid but thanks for the help

 

i check the fluid it is good the shifter linkage is still a little loose but i cant get it any tighter. the filter is newer so i dont think that is the problem. when i shift into reverse it grabs but when i shift into drive you can hear it try to grab but it doesnt completely grab. does anyone have any ideas or would it be an internal problem?
