Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Thanks guys for the input but I do not have the HO, unfortunately. Was wondering if the pcm would just relearn the transgo hd2 reprogramming kit by itself or if I have to to get it flashed? it was kinda rough today pretty hard shifts from 2-3, some times its good and some times it like ugh man rough...i got probably 100 miles on it since i did the (white connector) solenoid block and transgo kit, figured it would work out by now...Another fella on here told me to get it flashed so I'm starting to lean towards it. and by the way I think Heman is reaching for flander's sword while playing with his!!

Don't wast your time with a flash. Its not gonna do anything. The resistor is running the show now and modifys the value the tcm sees. Check your resistor connections and make sure they're good. They should be soldered for a good connection.

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Ran totally fine today, thanks cheap jeep for the info and i did solder the resistor in when i did it, just guess it had to take some time to figure the parameters...got the solder burn to prove it hot! upside down soldering kinda of reminds me of overhead welding.

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Welcome to the garage.
Did you check the fluid level and check for burned smell?
It most probably is het LR solenoid in the solenoid block which doesnīt work, so swapping the other block in should solve that.
The transgo kit makes the shifting faster. The biggest advantage is that it makes the overlap time (the time that two clutches are activated at the same time), less, so that there is less wear on the clutch packs.
After installing the kit some shifts can be harsh, but the TCM has to relearn the changed shift behaviour and that takes a bit of time.
I didnīt do the snip, so canīt tell you about that.

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Are you sure that the solenoid block that you have put in is ok? A low line pressure can already cause slipping clutches. Did you put a new sealing plate in between the solenoid block and the valve body, because the thin rubber lines on this seal plate easily break or get damaged and will cause internal leak and low(er) line pressure.
You did check the fluid level with engine running and it was ok ( not too low and not too high). Best is to check when hot, but when it slips you better don't drive it too far, or it will cause extra wear to the clutches or even completely wear one or more clutches. The cold level check will at least give a safe indication of the level.
You didn't install the shiftkit?

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

I took the solenoid out of a working tranny I was just going to put the whole valve body in instead if swapping just the solenoid block would that have been ok? My buddy checked the gasket on the solenoid and said it was fine there were no cracks or anything I did just watch a video and it said to tighten down the the 2 bolts with arrows on the valve body that hold down the solenoid block first I didn't read that anywhere befor I did it tho should I get another solenoid or just swap the tranny out completely or just swap the whole valve body with the solenoid together and not separate them because I can get another whole tranny like I did this time and for the price I can get it is the same price as just the solenoid or could it be something else thank you for the fast response also

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Did you use the spare transmission before that you know its ok? If it was sitting for a long time you never know what can happen.
Didn't' understand what you wrote. Thought that you swapped the complete valve body with solenoid block, but then you say that the sealplate was checked. I removed my solenoid block twice, and in both cases the sealplate had minor damage to the seal. Also my transmission was overhauled once due to slipping third gear and the shop found a worn clut h pack and a seal damage on the sealplate.
Can you get a transmission that cheap, because the solenoid block
costs around USD 280.
Fluid level is ok?

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Fluid level was dead on when hot I swapped just the solenoid block I was asking if if would have been ok to just swap valve bodys without taking the solenoid block off of it and yes I saw the jeep run and drive befor I got the tranny out of it and theres another jeep there that runs and drives fine that i can get the tranny out of from the same guy for 250usd

Re: Did shift solenoid & Transgo hd2 kit, flash or dont have to?

Then it was indeed easier to swap the whole valve body with the block. I would have a look at the solenoid block seal plate first or even better get a new one before opening the tranny. Take care that there are black receptacle (old type) and white receptacle (new type) solenoid blocks, which are using different types of sealplates.
