'96 cad trans

One of my fellow workers Mom's car. '96 Cad Eldo 4.6 N* It has 74,000 miles. Trans seems to take off in 3rd no shift, can't manually shift it either. Had code 741 TCC off. Fluid clean as can be, Any ideas?

Thanks

Larry...

...the diagnostics for the 4T80 are excellent so if you have access to AllData or Mitchell you can probably work thru using that. if not, PM me and I'll do some research and fax you the chart(s).

as a sidelight...they had alot of trouble with solenoids breaking on them (this is how I ended up with a 93 Seville)...if you drop the pan, you'll be able to see the solenoid(s) and it'll be obvious...the solenoid was so displaced on mine that the shift valve was sticking out thru the valve body. 80 bucks for solenoid kit, VB gaskets and a pan gasket from the dealer. there is a bulletin with part numbers. good luck...oh and BTW...i don't think the code is related

mine has 155k on it and is plenty strong...those transmissions are tough

I will look for bulletins tomorrow I can't access the GM site at home right now due to changes.I will also look up the code diagnostics for 741.I'm sure you know 3rd gear is the default gear on Gm transmissions.

If you still need the 741 chart after replacing the solenoid let me know I printed it out.

Davo,

I need what ever you have.

Called a trans part wholesaler who was very knowledgeable of this trans. He claims the 741 code is a problem. He states '96 is the only year for a viscous coupling in the TC. He further states they have a habit of breaking and therefore the 741 code. And because the 741 code trans goes in fail-safe.

One of the shift solenods is definitely broken, but no code because it is still electrically connected. Right on the money as far a $81 for soleniod pack and gaskets.

We are going to replace them and see what it nets. Was told trans cannot be taken out with removing eng-trans assy.

Putting in the solenoid kit took care of the problem. Had a hard time figuring out what the bracket was for in the kit. The one that now holds in the screen instead of the soleniod doing it. Thats what breaks the soleniod off, the line pressure trying to push out the screen.

They put a piece of paper saying refer to the TSB. They should of just put the diagram where the bracket goes with the kit (Was a Delco part)

My friend is very happy now

Thanks again
