ok so i changed my converter today and now the damn thing wont go. i can change the gears and all but it just wont move. i put a 8 inch stall in around 4800 stall turbo action. now i didnt have this problem before i changed stall so whats going on. i checked the fluid and it reads full on te stick has stock size pan, i knwo the converter had some fluid in it when i put it in but of course it wasnt full. any help would be great.

 

Make sure your HENWAY is operating properly.

 

whats a HENWAY

 

About 2 pounds

 

I'm wondering about the converter splines. What transmission is this on?

An early 700R4 needs a 27 spline converter. The later 700R4's use a 30 spline converter. If you have a 30 spline converter on a 27 spline shaft then the converter isn't turning the hydraulic pump in the tranny. One way to check is to put a pressure gauge on a port to see if there's any hydraulic pressure.

 

ROLMFAO, you beat me to it

 

I needed a good laugh and the setup was perfect. I was going to reply anyway as you can see above.

 

this is in a th 350 tranny, this was used in a power glide tranny before but the guy i got it from told me it would work in a th 350. i am glad he told me to try it out first before i bought it from him. will this work in a th 350 scince it is from a power glide?

 

Original PG input shafts were course splines and had their own converters. If he said it will work in a turbo tranny then his PG has an aftermarket shaft with turbo splines like in mine that allows you to use the more common turbo torque converters. After spending $1200 for a race converter for my TH400, I didn't want to buy another one when I switched to a PG.

So all you did was change the converter? Nothing else disassembled?

I can only think of a couple of things.

1: A cooler line is kinked. Steel line got bent or a rubber line to the cooler got kinked. Fluid flows from the pump, through the cooler then back to the tranny to be used.

2: Torque converter bolts not installed? Hey I'm looking at every option.

3: How far away was the torque converter from the flexplate before it was pulled up to be bolted up? Maybe the distance was too great and the converter was pulled off the splines. A spacer between the converter and the flexplate would have to be used to make up the excess distance.

3a: Is the flexplate on backwards making the distance too great?

4: I'd still check pressures.

5: Some race converters need a stator support bushing installed in them to work. My 8" already came with it installed. I'm not sure what happens if it's not installed.

 

yes the converter bolts are installed, i did put a 1/8 shim between the converter and flywheel. he said to push the converter all the way in and pull it out about 1/8 and then shim it from there so i did that atleast i thought. maybe i need bigger shims so the converter sits back in the tranny more? all i did was mover the tranny backwards so i could get the converter out disconnected the cooler lines, vacum bolts of course and then reinstalled everything i will triple check but i am sure i got everything. i never did take off the flexplate either so thats on right but thanks for the help so far.

 

ok so i toke out the shims and it now moves, sometimes. i used to be able to feel the car go into gear but now i cant. if i put it in to reverse i cnat tell if its in gear or not until i rev it up. sometimes its not and sometimes it is. i dont knwo if this is a cable problem or a flid problem. the stick say i have fluid but not sure if its right or not, it a bradied lokar line. so i guess i will mess with the cable and see what happens any suggestions

 

Depends how much you're actually reving it up. With a high stall 8" converter, you're not going to feel it going into gear like with a factory stall converter. At the lower rpms, the converter is doing a lot of slipping. I've never really looked at my tach while moving my car around but I know it won't move while at an idle. My converter stalls at 5700 rpm on the transbrake but it's still driveable.

If I put my car in gear and hold the brakes, pushing down on the throttle makes the car want to push ahead very easily. Just at a higher rpm than normal.

Hard to say exactly what you did.

Check linkage adjustment
Check fluid level
Check tranny oil pressure

If in doubt, swap your old converter back in and see if it works normal again.

 

when i had the old comverter in there i could feel the car jerk i guess you could say. i knew it was in gear whatever gear it was. this new converter i can shift it into any gear and i dont know if its in gear or not until i rev it up. when i rev it up if it does go into gear its not very hi i have to rev it when it doesnt go into gear i can rev it up to 6000 and it doesnt move. i was thinking about draining all the fluid out and starting over with that, drain the pain atleast. i shuold get aout 5 quarts to come out right with a stock style pan. the add about 5 in and the level should be right. i really dont want to pull it all back out and change it back to the old converter. i may just not be used to this style of converter like my old one. my old one was a b&m hole shot 2800-3200 stall, so this one is a big difference. do you usually feel it go into gear with a small converter. i know when i am the track i see race cars being sfited into gear. well thakns for the info so far i will check all of what you have said.

 

ok so i put my old converter back in and filled it with fliud put about 4 quarts in it and it wont go or still cant feel it going into gear. just sits there and revs up no matter what gear i out it into. i had a friend climb under car and look at cable to see if it was moving and it was so i guess something inside tranny?

 

Drop the pan and look to see if the S-link fell off the shifter spool. It's possible when you had the cable off that the shift lever rotated enough to allow the S-link to come off somehow. Without the S-link, the shifter spool won't slide in and out and supply fluid to the proper circuits.

 

well today i was going to put in some fluid and see if it was just low or something, well i got home from work and there was a huge puddle of trans fluid on the ground from the tail shaft back to the rear of the car as wide as the car. so i am just getting it rebuilt with all the good stuff i am tired of messin with it and that way i know everything is good and new. thanks you all your guys help.
