I have a TH400 in my Nova. It was fine last time I moved it. Now when I put it in gear it kills the engine.:( If I hold the "Rs" up it will go into gear but very hard. Forward is same as reverse. I didn't go far enough to see if it shifted. When you stop it has to be put into nut. or it will kill the engine... Engine 454 chevy so I don't think its a power thing may be converter????
sounds like N switch still is the rod locking the coulmn take that off
Guess I don't understand "N" switch the neutral safety switch isn't hooked up yet. the engine starts OK I just can't put it in gear with out killing the engine the only wires coming out of trans are for kick down?
gm had a steel rod that hook to the coulmn then to the tran s shifter lever.. lock out .. then to n switch in coulmn if you can not shift it the rod is out of adjustment or hiting on ex old n switch is still in the coulmn less you by past it .. was coulmn shift at one time
It is column shift but no neutral safety sw thats all been by passed for now.. The engine is not being turned off It is being boged down.
spool valve in trans valve body . hook to shift lever . try to go in two gears at the same time???Quote:

it s in the valve body?? but first unhook the shifter put trans in park try to start it in parkQuote:

Think I'll put in a drain plug while pan is down
i have to look at the flow chart but one of the valves may have pick up some junk i know if the reverse feed port is pluged then it will lock trans up in low 1 .did this trans have rubber check balls in it if so one came a part ?
That could be this trans sat for about 2 years but it did work the first time...I changed the filter and gasket it wasn't dirty inside but who knows I'll see if I can find flow chart on web.
i have a 400 book some were ? see what you can find on the net if not i see if i can find it .go back and look at my post did you see what i added this trans will lock up if r port is blocked it will lock up L1 i never use paper /cloth fillter i use a sreen fillter abit hard to find but the ony way to go
The only way I'm going to find out is pull the valve body... If I remember right the filter is paper or foam inside a metal housing.... don't know about checks
the paper are ok but can plug up and burn clutchs up .screen filters will not so EZ trans go may sell them?Quote:

check napa atpi-4954 ??? not sure if brass screen fillter
Thanks nothing like going to the store with parts numbers... They have a sigh over the counter that reads"The wrong information will Guarantee the wrong part every time"
found NAPA # 1-3999 ordered it but don't know what material it is... No big deal if it's not right they can send back. The # you gave me is no longer avaliable. I'm leting it drip so I can work under there with out an oil bath lol
Got a few extra minuites and pulled the valve body All spools are free all springs good. I will clean it up in the morning got it soaking in Mineral sperits.
Well took it all apart found nothing wrong, dirty, or missing. Figured I'd change yokes while I had it apart . Parts store had to order U joint won't get it till Monday. So I guess I'll work on the 57.
Pat anyother sugestions??
try it with the drive shaft off ? rear brakes hanging up .bad valve body gasket ?
OK After puting everything back together I did try it without the drive shaft. It worked like it was suposed to????? The brakes can't be the problem it rolls and it would kill the engine at stop signs anyway... When I get the new U joing monday I'll try it again... maybe there was something in the valve body but everything seemed clean.
well you never know small chunk of something in there . or maybe it just wanted you to give it a bath :)
OK :D you called it right Pat Thanks :3dSMILE::3dSMILE: Put new U joints in put Drive Shaft in and it works just like it should...... Must have been somthing in the valve body ?? I love it when things work the way they are suposed to. ;) Thanks again
good deal... now you can do some hot rubber black topping on some roads .not that you would do that
:eek: WHO ME???? No now I have incentive to finish body work:LOL::LOL:Today they did that Michigan black top sealing crap where they pour tar on the road then pea gravel over that. Great for your cars finish..
yep chip n seal.... roads :( come to michigan ... drive on are... crappy roads ...Quote:
