TH 400 issues

[Alss]

I knew I should have stuck with a manual trans..anyway Th 400 is making noise..a whirring sounds while driving..also really bangs hard when you put it in reverse..hot or cold.please tell me its cooked so I can convert to a 4 -5-6 speed ..seriously trans has maybe 1500 miles on it..not a drag racer but I am not easy on it. Shifts OK..too fast for my liking but Im not done playing with the governor..the banging in reverse has me worried..fluid seems clean no noticable metal in it..any ideas?? Thanks

Al, whirring sounds like the pump is going out, I am a shifter guy myself but a good auto with your combo sounds real fun to me, pop it out and give it one more go with your trans guy, have him drive it before yanking it is good advice.

if it craps out again order up the TKO 6spd kit.

peace. B.

Bud, I'm not pulling anything until I KNOW what the problem is if there is one,,could be loose nut behind the wheel syndrome ...and it wouldnt be a TKO..the Richmond 6 is sitting on the shop floor!!

Thanks!! have something else in the works with a stick , so I will "stick" with the auto.

Found another good case and will start from scratch..thinking I will "add" some hp later on so need to know whats there..I HATE changing transmissions!!..so I will be taking suggestions on whats good and not good on a TH 400..everone has good guys they deal with Im sure..I have one too... so lets just cover the tech areas..or if there is a thread..the search function hates me too..thanks guys..IM ready for school!!

Definately get an after market 34 element sprag if it doesn't have one already. Trust me, I cooked a stock piece with a mild 454 in my 70.

Al: give me the who/what/when/where of the noise. All the time, in gear stopped, only when moving, etc...also more specifics on the banging. Also, any idea how your guy setup the trans as far as line pressure...new converter?

Rob I have no info on the trans..was "supposed" to be built ready to go..had 1000 miles on it when I got it. Previous owner had been playing with the modulator trying to get it to shift later..Ive been working on the governor with good results..nioses..makes a whirring sound when driving..I can hear the planetaries going with the speed of the motor..the bang is when I put it in reverse..rocks the whole car!!..other than that works OK if I manually shift it..using the go pedal it shifts at about 5100..I need to play with the springs more..just got a floor shifter so I can manually shift..some say the drum is bad some dont know. I want to change the converter for sure but I can do that when I change the motor..thoughts??

Thanks
