antil33t 90 Report post Posted August 8, 2012 Do you need an EH? My E30 has an EH with sports mode and other bs, and the M20 is being removed for an M52.. so I won't be needing it. Quote Share this post Link to post Share on other sites

BM WORLD 1283 Report post Posted August 9, 2012 Do you know if you can use the later "non electronic" box to replace the 4HP22EH electronic?why would you want to despec teh car by doing that the eh type is upspeced thing and they work much better at changing gears than the basic low spec kick down cable type of trans . why do you think all the newer bmw's use a sports ,ecno ,manual switch on there trans. , but yes you could fit one of the older basic type ones in there , just as long as you get the kick down cable and brackets etc to hook upto the throttle body etc Quote Share this post Link to post Share on other sites

Was looking at a trans from 1990 model without the sport mode switch so not an "older" type.. Quote Share this post Link to post Share on other sites

polley 916 Report post Posted August 9, 2012 The EH model isnt that much flasher... If you're worried about it been "fun to drive" manual convert it. Quote Share this post Link to post Share on other sites
Deano 1 Report post Posted August 10, 2012 I know manual is the preferred option but the question was: Will the later hydraulic auto (4hp22) work in the E30s with the 4hp22eh electronic boxes? Anyone? Quote Share this post Link to post Share on other sites

Anyone? NO. but if removed all the good mech parts from the std box and fitted them to your EH box then yes, Quote Share this post Link to post Share on other sites
polley 916 Report post Posted August 10, 2012 Yes it will. Just need kick down cable and brackets Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2132 Report post Posted August 10, 2012 Yes it will. Just need kick down cable and brackets this. will definately bolt up etc etc. only issue i can see you running into is it may have inhibitor wiring issues though, something to research before you get stuck in.

antil33t 90 Report post Posted August 10, 2012 Yes it will. Just need kick down cable and brackets and remove all the faggot wiring from the boot for the TCU. EH fitted cars have a different TPS too. Quote Share this post Link to post Share on other sites
polley 916 Report post Posted August 10, 2012 You can leave the tps and wiring etc in place... Quote Share this post Link to post Share on other sites

Inhibitor is part of the gear selector, so wont be a problem. Quote Share this post Link to post Share on other sites
Deano 1 Report post Posted August 19, 2012 FYI: In the end bought a complete trans from 89 525i. It was an EH so had the same electrical connection on the side which means it has the same valve body assembly and that being version E7 5 solenoid type. The only difference was the gear stick connection was on the drivers side as opposed to left side. This can be made to work for the E30 but the other way ie E30 trans to 525i would have to be drilled as on the E30 trans there is no hole for the rhs gear select shaft. Few other things to check when looking at 4HP22s is size of the toque converters as apparently 3 different sizes and the output flange can be 3 bolt or 4 bolt. So the problem turned out to be the MV5 solenoid which is the main pressure control valve which explains why there was no drive at all, no pump pressure. Here is the tech guide ZF_20Tech_20Guide.pdf Quote Share this post Link to post Share on other sites
polley 916 Report post Posted August 19, 2012 Yeah, they have different output flanges and also different tail housings depending on what they were used for. Bell housings also different depending on what it came off. All easy stuff to swap over though. Quote Share this post Link to post Share on other sites
