I have a Turbo 400 and a Torque converter that were built by a company named Select Performance in New York I believe. I have no idea how long ago as they were on the car when I bought it. When I first started driving the car late last year all was ok. Then I had a car show and on the last day of the show when I went to leave I put the car in reverse and nothing. I turned the car off and turned it back on and it went into gear and off I went. I did notice that the car did not shift as hard but thought nothing of it.

Fast forward two months till today. I bought a new Trans pan and I wanted to install it. I had to change the oil pickup as this pan was a bit shallower. I put everything back together went to go cruise around the block and I put it in reverse and nothing. the engine does not even idle down like it is in gear. I reved the engine a bit and nothing. I know nothing about Transmissions but what do you guys think it could be? Money is definitely an issue, but I imagine that I will need to take it to a trans shop.

I'd check the 3 bolts that hold the converter to the flexplate as a start.
Then the flexplate to crank bolts.
The fluid level.
The shift linkage.
That's a start.

 

[Barcochris]

Shift linkage is oK I will check the other parts tomorrow.

I forgot to add this is a Reverse manual valve body as well.

 

[Barcochris]

Checked the bolts all are fine.

 

[Mike]

Internal linkage OK?

Internal linkage OK?

Not sure how to check that. a little guidence would be awesome.

 

[Mike]

Drop the pan and see if the link is still connected to the valve body and external shift arm.

 

[Barcochris]

Ok, Thanks. I will check it out.

 

[Barcochris]

Talked to the comapny that built it and he said that he thought it would be a pump issue

Checked all that and it was all moving/ working. So Trans is out of the car and going to the shop in the Am

 

[Mike]

Feel any resistance when you turn the converter?

 

[Barcochris]

No, not that I can think of.

 

[Mike]

Post back when you get some info from the shop.

 

[Barcochris]

ok, here is what they told me.

The converter was to short for the pump. wore about an .125 grove in the pump. Pump is shot as well as the clutches..

I am not sure I understand the to short part, but I am going in tomorrow to talk about rebuilding it.

Basically it sounds like the converter was too far from the flexplate and instead of using spacers it was pulled up to the flexplate. This left insufficient engagement in the pump. If I remember right the converter should be pushed all the way into the pump and pulled out no more than 3/16 of an inch. If it has to then washers should be used between the flexplate and converter.

 

[Barcochris]

I know it was further than 3/16.

When i recived the engine and trans I took it apart, I know there were no spacers when i took it apart. But that does not mean it was right at that point. Thanks for the information. So when i install itI push it all the way in and then pull it back about 3/16 and shim between the flexplate and the converter correct?

Heres some info:

Was your converter modified for a thick or spaced flexplate?

I have no idea. I don't think I have a thick flexplate. I will get more info when I go in tomorrow.

 

[Barcochris]

the article posted said If you have more than 1/16 to 1/8 install washers. I knwo I had WAY more than that. I wish I would of had that info sooner. But like I said. I think it was on the way out since this is how it was set up prior to me

 

[Mike]

That article has some good info ,but it doesn't tell you that the converter still needs to index in the crank.
It's possible to over shim and not have the converter in the crank.
Might need to shim the flexplate if that's the case.
