hi everyone, I am looking to do a transmission service on my 96 XJ6. I had the service done about 30k ago, but wanted to dot it again because I feel like the tranny needs some service done. Upon doing it I wanna have the complete service done, what does that require? Changing fluid and filter? and is that it? I would like the complete tranny service done. thanks.

 

There are two methods.

1) Remove pan, replace filter. About 4 quarts of old fluid will come out..leaving about 5-6 quarts of old fluid in the trans. But...you get a new filter.

2) "Flush" transmission. Messy and awkward to DIY but most any repair shop offers this service. A machine is used to pump out ALL old fluid while new fluid is being pumped in. The pan and filter stay in place.

Method #2 is usually considered more useful. It typically runs $100-$140 or so. Some worry about the filter not being changed but, IMHO, if the filter is clogged your trans is probably on its last legs.

In rare instances problems have occured after flushing presumably because procedure knocked loose debris or sludge that previously had been sitting harmlessly...and was now fouling the passageways and hurting the machinery. Again, this would be on a transmission that is old and/or worn enough to have accumulated lots of crud.

Method #1 can be repeated 2-3-4 times with some driving in between. What you're doing is mixing old oil with new and eventually what's left in the trans will be mostly "new".

Cheers

As always, Doug has posted some excellent advice and I agree with all of it. Personally, I would opt for his option #2 for the same reasons he sites, but I would also add a bottle of Lucas tranny conditioner. Helps with the sludge issues Doug mentioned, and really does keep things cool and chirpy. I put the stuff into a C4 that had boiled twice and it ran another 100'000 clicks. I add it to all the auto boxes I encounter now with good results.

 

Wanted to change transmission fluid on my 96 XJ6 and got a price from dealer for $360. Includes filter, gasket, filter o-ring, and Installing a new rear seal. I asked about the rear seal and they said sometimes these will leak. Also on the 95 xj6 there is a drain plug, on the 96 there is not.

 

My '96 VDP has a drain plug...
