Anti clunk spring

Hi all,
Can anyone help me locate an "anti clunk spring" replacement block. The case in my turbo 350 trans is almost worn through where the low/reverse roller clutch and the anti clunk spring come toghether. There is supposed to be ablock that is used in place of the spring and will alow you to use the case again. I've searched everywhere with no success! Thanks!
Joe

the problem with the 'block' piece you describe is under a high load situation the center support can split since only one spot is holding the power.

NATPRO lists these repair items you are looking for in their catalog....

1 piece is #GM-1026

4 piece kit is GM-1025

The 4 piece is a better design, IF it is still available.

=========

A better solution is the center support that has been machined for a plate that bolts onto the center support and lugs into ALL the non worn area of the case lugs in the trans case.

Is there some attachment that you have to this particular case? I see th350s in the classifieds for around $200 occasionally.

Anti clunk spring

Hey Crosley!
Thanks for the reply! I see where your going with the block under high load. In a stock situation would it be a user? I like the set-up that has been machined for a plate that bolts onto the center support and lugs into ALL the non worn area of the case lugs in the trans case. What would I be using, the used steel plates machined to fit? No kits like that? Sounds like the machining might be expensive. New case better $ wise?

I could not find online parts at Natpro either.

I did find a 4 piece kit online. click here.

I know and have seen the "good" one that Crosley mentions. Transtar sells it. I"m still trying to find it.

Tony, does Transtar sell it too? I've seen the guys at Aamco install the one you mention and they use Transtar. Very good part.

I do not know... we have the plates water jet cut, coated, the center supports machined... all in the USA.

I've found mention of it online, but have not found a picture or a place that sells them. They referred to them as a "center support case saver".
Give Transtar a call tomorrow. They have warehouses in different states. I just caught a glimps of the one I saw them use. It was similar looking to the center support and bolted onto a modified support plate. (I think! LOL)

Mark

Transtar industries

AH...Haaaaa!!! I found one! LOL Second picture down. 65 bucks. It's a "thin center support" that has been drilled and tapped and then another like piece is bolted on.

Center support case saver.
