Help with Tranny please
 

Every morning I back out of my garage and onto the street. When I shift from Reverse to D,, there is a delay of about 3 or 4 seconds before the gear engages.

It's only the first shift of the day,,, otherwise the engine and tranny perform beautifully. I checked the fluid level in the tranny and it seems fine. I do not know for sure when the transmission last had a fluid/filter change.

Any ideas what could be causing this? Is this a sign of worse things to come?

Car is a 1993 300CE cabriolet with 90k (head gasket and wiring harness relaced by PO).

Thanks!

that's a pretty good indication that the trans has worn out the reverse clutches.will need at minimum a mini rebuild.but at least it's management by design not crisis.

He is correct!!!!!!!!

Thanks for the reply David.

The reverse-to-Drive delay only happens on the first shift of the day,,,,, it goes from reverse-to-drive just fine after that,, dunno if that's relevent.


'Mini-rebuild' has the same kinda feel as the phrase 'minor nuclear war' ,,,,, is this something I should get a local indy to perform,,,, or is it something for AAMCO? In your opinion,,, how much $ am I looking at,, ballpark?


Anything else I should be doing to a 90k tranny while it is off the car?

Thanks again.

i charge about $850 for a mini rebuild.this involves taking trans out of car,remove front pump and replace the o ring that kills most of these trans when it starts to leak.then remove front drum and replace clutches and lower seals in drum.then pull out the reverse clutches and replace them.reassemble and then take out valve body and main plate,disassemble and clean govenor screens,new filter and pan gasket and replace.where any seals and o rings are exposed they get replaced.-------the two main things that wear have now been covered.

Thanks matey,, wish I lived closer so you could do the work.

Most likely cause of a delay INTO DRIVE is a leak in the B2 circuit, B2 piston seal and or a sticking B2 valve in the Valve body.
