jmod (not a repost)

hey everyone, i heard a while back from some post that i dug a few pages deep for that doing a jmod on a transmission that was slipping or acting improperly would kill it.

ive got around 95k miles on mine, and it doesnt slip, it just takes its sweet time to shift from gear to gear, usually i have to let off the gas before it shifts.

would a jmod fix that? or could it make it worse?

im beginning to think that they may have been thinking about a shift kit

not really, but if yours trans isnt going into gear, i'd say it needs to be checked. it could be that you just need to add some. also, you should probably change the filter anyways, so do a complete flush/refill with merc V.

I'm no expert here. However i just did the Jmod about 2 months ago. You replace the shift accumulator pistons when you do this, so that could help out the situation with the slow shifting. The Merc 5 could play a big part too.
Either way, if the trans is on its way out, its gonna go no matter what you do or dont do.

I doubt it, but its simple to follow the article so if you had the parts and information they should be able to do it for you. The j-mod itself is designed to help your transmission so if you had a failure its most likely from the condition its already in. Remember to either use mercon 5 or friction modifier like dr.tranny etc if you use mercon 3.

The heck with "checking" the fluid. It probably needs to be CHANGED. Upgrade the accumulators, stick a Jmodded valve body in it, fill it with Mercon V and be amazed at the difference.

I doubt the local transmission place would be familiar with the Jmod but it wouldn't hurt to ask.

Mods? Yea, I got mods ...
